Changing an employment contract

Getting agreement

Usually, the employer and employee both need to agree to any contract changes. But an employee can insist on a change if they have a legal right to it.


You must get an employee’s agreement if you want to make changes to their contract.

You should:

  • consult or negotiate with employees or their representatives (for example from a trade union or staff association)
  • explain the reasons for changes
  • listen to alternative ideas from employees

You may also want to talk with workers, asking them about their future plans. With older employees this can include talking about their thoughts on retirement and their options for staying in the job, for example changes to their role, hours or working pattern.


Explain to your employer why you want to make the changes. You can insist on a change if it’s covered by a statutory right - for example not working on a Sunday.
