At a guess (IANAL), they don't have to change the law in order to vary the terms of employment of civil servants. The employment contract itself will describe how the employment contract can be changed, subject to being able to demonstrate reasonableness in an employment tribunal.
It could be (depending on the contract, which, of course, I've not seen) that the government can vary that deal and the employee's only alternative to accepting the change is redundancy with statutory redundancy pay.
The redundancy arrangements for civil servants are far in excess of statutory redundancy pay, which is one week's salary (capped at £380) for each full year of service (capped at 20 years). That's all I got when I was made redundant in late 2008, so my sympathy with civil servants is limited. (-8
