7.—(1) A contract of employment between the MMC and a person who is employed by the MMC immediately before the commencement date is to have effect from the commencement date as if originally made between him and the Commission.
(2) All rights, powers, duties and liabilities of the MMC under or in connection with a contract to which paragraph (1) applies are transferred to the Commission on the commencement date.
(3) Anything done before the commencement date by or in relation to the MMC in respect of such a contract, or in respect of a person employed under such a contract, is to be deemed from that date to have been done by or in relation to the Commission.
(4) Paragraphs (1) to (3) are without prejudice to the right of an employee to terminate his contract of employment if his working conditions are changed substantially to his detriment; but such a change is not to be taken to have occurred by reason only of the application of this article.
