PART I GENERAL AND INTERPRETATION

Citation, commencement and interpretation1

1

These Regulations may be cited as the Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 and shall come into force on 1st July 2000.

2

In these Regulations—

  • “the 1996 Act" means the Employment Rights Act 1996 M2;

  • “contract of employment" means a contract of service or of apprenticeship, whether express or implied, and (if it is express) whether oral or in writing;

  • “employee" means an individual who has entered into or works under or (except where a provision of these Regulations otherwise requires) where the employment has ceased, worked under a contract of employment;

  • “employer", in relation to any employee or worker, means the person by whom the employee or worker is or (except where a provision of these Regulations otherwise requires) where the employment has ceased, was employed;

  • “pro rata principle" means that where a comparable full-time worker receives or is entitled to receive pay or any other benefit, a part-time worker is to receive or be entitled to receive not less than the proportion of that pay or other benefit that the number of his weekly hours bears to the number of weekly hours of the comparable full-time worker;

  • “worker" means an individual who has entered into or works under or (except where a provision of these Regulations otherwise requires) where the employment has ceased, worked under—

    1. a

      a contract of employment; or

    2. b

      any other contract, whether express or implied and (if it is express) whether oral or in writing, whereby the individual undertakes to do or perform personally any work or services for another party to the contract whose status is not by virtue of the contract that of a client or customer of any profession or business undertaking carried on by the individual.

3

In the definition of the pro rata principle and in regulations 3 and 4 “weekly hours" means the number of hours a worker is required to work under his contract of employment in a week in which he has no absences from work and does not work any overtime or, where the number of such hours varies according to a cycle, the average number of such hours.

Meaning of full-time worker, part-time worker and comparable full-time worker2

1

A worker is a full-time worker for the purpose of these Regulations if he is paid wholly or in part by reference to the time he works and, having regard to the custom and practice of the employer in relation to workers employed by the worker’s employer under the same type of contract, is identifiable as a full-time worker.

2

A worker is a part-time worker for the purpose of these Regulations if he is paid wholly or in part by reference to the time he works and, having regard to the custom and practice of the employer in relation to workers employed by the worker’s employer under the same type of contract, is not identifiable as a full-time worker.

F13

For the purposes of paragraphs (1), (2) and (4), the following shall be regarded as being employed under different types of contract—

a

employees employed under a contract that is not a contract of apprenticeship;

b

employees employed under a contract of apprenticeship;

c

workers who are not employees;

d

any other description of worker that it is reasonable for the employer to treat differently from other workers on the ground that workers of that description have a different type of contract.

4

A full-time worker is a comparable full-time worker in relation to a part-time worker if, at the time when the treatment that is alleged to be less favourable to the part-time worker takes place—

a

both workers are—

i

employed by the same employer under the same type of contract, and

ii

engaged in the same or broadly similar work having regard, where relevant, to whether they have a similar level of qualification, skills and experience; and

b

the full-time worker works or is based at the same establishment as the part-time worker or, where there is no full-time worker working or based at that establishment who satisfies the requirements of sub-paragraph (a), works or is based at a different establishment and satisfies those requirements.

Workers becoming part-time3

1

This regulation applies to a worker who—

a

was identifiable as a full-time worker in accordance with regulation 2(1); and

b

following a termination or variation of his contract, continues to work under a new or varied contract, whether of the same type or not, that requires him to work for a number of weekly hours that is lower than the number he was required to work immediately before the termination or variation.

2

Notwithstanding regulation 2(4), regulation 5 shall apply to a worker to whom this regulation applies as if he were a part-time worker and as if there were a comparable full-time worker employed under the terms that applied to him immediately before the variation or termination.

3

The fact that this regulation applies to a worker does not affect any right he may have under these Regulations by virtue of regulation 2(4).

Workers returning part-time after absence4

1

This regulation applies to a worker who—

a

was identifiable as a full-time worker in accordance with regulation 2(1) immediately before a period of absence (whether the absence followed a termination of the worker’s contract or not);

b

returns to work for the same employer within a period of less than twelve months beginning with the day on which the period of absence started;

c

returns to the same job or to a job at the same level under a contract, whether it is a different contract or a varied contract and regardless of whether it is of the same type, under which he is required to work for a number of weekly hours that is lower than the number he was required to work immediately before the period of absence.

2

Notwithstanding regulation 2(4), regulation 5 shall apply to a worker to whom this regulation applies (“the returning worker") as if he were a part-time worker and as if there were a comparable full-time worker employed under—

a

the contract under which the returning worker was employed immediately before the period of absence; or

b

where it is shown that, had the returning worker continued to work under the contract mentioned in sub-paragraph (a) a variation would have been made to its term during the period of absence, the contract mentioned in that sub-paragraph including that variation.

3

The fact that this regulation applies to a worker does not affect any right he may have under these Regulations by virtue of regulation 2(4).

PART II RIGHTS AND REMEDIES

Less favourable treatment of part-time workers5

1

A part-time worker has the right not to be treated by his employer less favourably than the employer treats a comparable full-time worker—

a

as regards the terms of his contract; or

b

by being subjected to any other detriment by any act, or deliberate failure to act, of his employer.

2

The right conferred by paragraph (1) applies only if—

a

the treatment is on the ground that the worker is a part-time worker, and

b

the treatment is not justified on objective grounds.

3

In determining whether a part-time worker has been treated less favourably than a comparable full-time worker the pro rata principle shall be applied unless it is inappropriate.

4

A part-time worker paid at a lower rate for overtime worked by him in a period than a comparable full-time worker is or would be paid for overtime worked by him in the same period shall not, for that reason, be regarded as treated less favourably than the comparable full-time worker where, or to the extent that, the total number of hours worked by the part-time worker in the period, including overtime, does not exceed the number of hours the comparable full-time worker is required to work in the period, disregarding absences from work and overtime.

Right to receive a written statement of reasons for less favourable treatment6

1

If a worker who considers that his employer may have treated him in a manner which infringes a right conferred on him by regulation 5 requests in writing from his employer a written statement giving particulars of the reasons for the treatment, the worker is entitled to be provided with such a statement within twenty-one days of his request.

2

A written statement under this regulation is admissable as evidence in any proceedings under these Regulations.

3

If it appears to the tribunal in any proceedings under these Regulations—

a

that the employer deliberately, and without reasonable excuse, omitted to provide a written statement, or

b

that the written statement is evasive or equivocal,

it may draw any inference which it considers it just and equitable to draw, including an inference that the employer has infringed the right in question.

4

This regulation does not apply where the treatment in question consists of the dismissal of an employee, and the employee is entitled to a written statement of reasons for his dismissal under section 92 of the 1996 Act M3.

Unfair dismissal and the right not to be subjected to detriment7

1

An employee who is dismissed shall be regarded as unfairly dismissed for the purposes of Part X of the 1996 Act if the reason (or, if more than one, the principal reason) for the dismissal is a reason specified in paragraph (3).

2

A worker has the right not to be subjected to any detriment by any act, or any deliberate failure to act, by his employer done on a ground specified in paragraph (3).

3

The reasons or, as the case may be, grounds are—

a

that the worker has—

i

brought proceedings against the employer under these Regulations;

ii

requested from his employer a written statement of reasons under regulation 6;

iii

given evidence or information in connection with such proceedings brought by any worker;

iv

otherwise done anything under these Regulations in relation to the employer or any other person;

v

alleged that the employer had infringed these Regulations; or

vi

refused (or proposed to refuse) to forgo a right conferred on him by these Regulations, or

b

that the employer believes or suspects that the worker has done or intends to do any of the things mentioned in sub-paragraph (a).

4

Where the reason or principal reason for dismissal or, as the case may be, ground for subjection to any act or deliberate failure to act, is that mentioned in paragraph (3)(a)(v), or (b) so far as it relates thereto, neither paragraph (1) nor paragraph (2) applies if the allegation made by the worker is false and not made in good faith.

5

Paragraph (2) does not apply where the detriment in question amounts to the dismissal of an employee within the meaning of Part X of the 1996 Act.

Complaints to employment tribunals etc.8

1

Subject to regulation 7(5), a worker may present a complaint to an employment tribunal that his employer has infringed a right conferred on him by regulation 5 or 7(2).

2

Subject to paragraph (3), an employment tribunal shall not consider a complaint under this regulation unless it is presented before the end of the period of three months (or, in a case to which regulation 13 applies, six months) beginning with the date of the less favourable treatment or detriment to which the complaint relates or, where an act or failure to act is part of a series of similar acts or failures comprising the less favourable treatment or detriment, the last of them.

3

A tribunal may consider any such complaint which is out of time if, in all the circumstances of the case, it considers that it is just and equitable to do so.

4

For the purposes of calculating the date of the less favourable treatment or detriment under paragraph (2)—

a

where a term in a contract is less favourable, that treatment shall be treated, subject to paragraph (b), as taking place on each day of the period during which the term is less favourable;

b

where an application relies on regulation 3 or 4 the less favourable treatment shall be treated as occurring on, and only on, in the case of regulation 3, the first day on which the applicant worked under the new or varied contract and, in the case of regulation 4, the day on which the applicant returned; and

c

a deliberate failure to act contrary to regulation 5 or 7(2) shall be treated as done when it was decided on.

5

In the absence of evidence establishing the contrary, a person shall be taken for the purposes of paragraph (4)(c) to decide not to act—

a

when he does an act inconsistent with doing the failed act; or

b

if he has done no such inconsistent act, when the period expires within which he might reasonably have been expected to have done the failed act if it was to be done.

6

Where a worker presents a complaint under this regulation it is for the employer to identify the ground for the less favourable treatment or detriment.

7

Where an employment tribunal finds that a complaint presented to it under this regulation is well founded, it shall take such of the following steps as it considers just and equitable—

a

making a declaration as to the rights of the complainant and the employer in relation to the matters to which the complaint relates;

b

ordering the employer to pay compensation to the complainant;

c

recommending that the employer take, within a specified period, action appearing to the tribunal to be reasonable, in all the circumstances of the case, for the purpose of obviating or reducing the adverse effect on the complainant of any matter to which the complaint relates.

F28

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

9

Where a tribunal orders compensation under paragraph (7)(b), the amount of the compensation awarded shall be such as the tribunal considers just and equitable in all the circumstances F3... having regard to—

a

the infringement to which the complaint relates, and

b

any loss which is attributable to the infringement having regard, in the case of an infringement of the right conferred by regulation 5, to the pro rata principle except where it is inappropriate to do so.

10

The loss shall be taken to include—

a

any expenses reasonably incurred by the complainant in consequence of the infringement, and

b

loss of any benefit which he might reasonably be expected to have had but for the infringement.

11

Compensation in respect of treating a worker in a manner which infringes the right conferred on him by regulation 5 shall not include compensation for injury to feelings.

12

In ascertaining the loss the tribunal shall apply the same rule concerning the duty of a person to mitigate his loss as applies to damages recoverable under the common law of England and Wales or (as the case may be) Scotland.

13

Where the tribunal finds that the act, or failure to act, to which the complaint relates was to any extent caused or contributed to by action of the complainant, it shall reduce the amount of the compensation by such proportion as it considers just and equitable having regard to that finding.

14

If the employer fails, without reasonable justification, to comply with a recommendation made by an employment tribunal under paragraph (7)(c) the tribunal may, if it thinks it just and equitable to do so—

a

increase the amount of compensation required to be paid to the complainant in respect of the complaint, where an order was made under paragraph (7)(b); or

b

make an order under paragraph (7)(b).

Restrictions on contracting out9

Section 203 of the 1996 Act M4 (restrictions on contracting out) shall apply in relation to these Regulations as if they were contained in that Act.

(This note is not part of the Regulations)

These Regulations come into force on 1st July 2000 and implement Directive 97/81/EC (normally referred to as the Part-time Work Directive) as extended to the United Kingdom by Directive 98/23/EC, in Great Britain.

The Regulations give part-time workers the right in principle not to be treated less favourably than full-time workers of the same employer who work under the same type of employment contract. In addition a right is given to workers who become part-time or, having been full-time, return part-time after absence, to be treated not less favourably than they were before going part-time.

The rights apply where the less favourable treatment is on the ground that the worker is part-time and is not justified on objective grounds.

The rights are exercisable by complaint to an employment tribunal.

A Regulatory Impact Assessment of the costs and benefits that these Regulations would have is available to the public from Employment Relations 5A, Department of Trade and Industry, 1 Victoria Street, London SW1H 0ET.

These Notes accompany SI 2000/1551 The Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 and are issued free of charge to all purchasers.

GUIDANCE NOTES

These notes are not exhaustive. They cover the main changes brought in by the Government’s proposals on part-timers. They only occasionally cross-reference to existing legislation, such as the Sex Discrimination Act 1975, which already covers part-timers. Fuller guidance is available on the DTI website at: http://www.dti.gov.uk/er/ptime.htm

Rate of pay

The Regulations have a direct effect on pay. As a result of the Regulations, part-timers must not receive a lower basic rate of pay than comparable full-timers.

Part-timers can only be given a lower hourly rate when this is justified on objective grounds. One example where a different hourly rate might be objectively justified would be a performance related pay scheme. If employees are shown to have a different level of performance measured by a fair and consistent appraisal system this could justifiably result in different rates of pay.

To comply with the law:

Part-timers should receive the same hourly rate as comparable full-timers.

Overtime

As case-law currently stands, part-timers do not have an automatic right to overtime payments once they work beyond their normal hours. However, once part-timers have worked up to the full-time hours of comparable full-timers they do have a legal right to overtime payments where these apply.

To comply with the law:

Part-timers should receive the same hourly rate of overtime pay as comparable full-timers, at least once they have worked more than the normal full-time hours.

Contractual sick and maternity pay

The Regulations apply directly to contractual sick and maternity pay. This means that there is an obligation on employers not to treat a part-timer less favourably than a comparable full-timer. The benefits that a full-timer receives must also apply to part-timers pro rata. The only exception will be if the different treatment is justified on objective grounds.

To comply with the law, part-timers should not be treated less favourably than comparable full-timers in terms of:

calculating the rate of sick pay or maternity pay;

the length of service required to qualify for payment;

the length of time the payment is received.

Occupational Pensions

Scheme rules may need to be revised, to ensure that they comply with the new legislation.

To comply with the law:

Employers must not discriminate between full-timers and part-timers over access to pension schemes, unless different treatment is justified on objective grounds.

Access to training

Under the regulations, there is an obligation on employers not to exclude part-timers from training. Training will need to be structured wherever possible to be at the most convenient times for the majority of staff including part-timers.

To comply with the law:

Employers should not exclude part-time staff from training simply because they work part-time.

Training should be scheduled so far as possible so that staff, including part-timers, can attend.

Leave/holidays/breaks: annual leave, maternity and parental leave; career breaks

Part-timers, like their full-time colleagues, are entitled to a minimum of statutory annual leave, maternity leave, parental leave, and time-off for dependants.

In some cases, companies extend these statutory entitlements with enhanced contractual conditions. When this occurs, part-timers should have the same entitlements as their full-time colleagues, on a pro-rata basis where appropriate.

In the case of career breaks, part-time staff should be treated no less favourably than comparable full-time staff.

To comply with the law:

The contractual holiday entitlement of part-time staff should be pro rata to that of comparable full-timers.

Contractual maternity leave and parental leave should be available to part-timers in the same way as for comparable full-timers.

Careers break schemes should be available to part-timers in the same way as for comparable full-timers, unless their exclusion is objectively justified on grounds other than their part-time status.

Redundancy

In a redundancy situation, part-timers should be treated no less favourably than their full-time equivalents. Different treatment of full-timers and part-timers will only be lawful if it can be justified on objective grounds.

To comply with the law:

The criteria used to select jobs for redundancy should be objectively justified, and part-timers must not be treated less favourably than comparable full-timers.

Objective Justification

The right of part-timers not to be treated less favourably than a comparable full-timer applies only if the treatment is not justified on objective grounds.

Less favourable treatment will only be justified on objective grounds if it can be shown that the less favourable treatment:

1

is to achieve a legitimate objective, for example, a genuine business objective;

2

is necessary to achieve that objective; and

3

is an appropriate way to achieve the objective.
