Airports Act 1986

3 It is hereby declared for the avoidance of doubt that—

(a) the effect of section 2 in relation to any contract of employment with the BAA in force immediately before the appointed day is merely to modify the contract (as from that day) by substituting the successor company as the employer (and not to terminate the contract or vary it in any other way); and

(b) that section is effective to vest the rights and liabilities of the BAA under any agreement or arrangement for the payment of pensions, allowances or gratuities in the successor company along with all other rights and liabilities of the BAA;

and accordingly for the purposes of any such agreement or arrangement (as it has effect by virtue of paragraph 1 in relation to employment with the successor company) any period of employment with the BAA shall count as employment with the successor company.
