If an employer wants to change a job contract to bring it up to date with legislation (not change hours or pay etc) do the employees have to agree ? If they dont sign it does that mean it doesnt stand or that it is accepted without signature ?
I don't know the official answer but I used to work for a high street bank that was taken over by another.
The time came when they wanted us people from the 'old' bank to sign new contracts for the 'new' one. We were told that we didn't have to but if we didn't, we wouldn't get any pay rises or benefits because these would all be negotiated under the 'new' contracts and anyone on the old would lose out.
Whether this was true or not I don't know, but everyone signed a new one!
An employer can offer you an amended contract at any time. If you don't sign but you continue working you will be deemed to have accepted the new contract by default.
If it's to bring your contract up to date with legislation they're within they're rights to amend it.
