Many thanks for your patience. It is certainly possible to try and negotiate such a contract but whether the employer actually agrees to it is another matter. Whilst you can propose these suggestions to them, you cannot force them to agree to them or implement them.
On the assumption that they do agree to your proposal and allow you to work for a fixed period with the on call feature, then it would be a legally binding contract that the employer would be expected to honour. However, as you have seen now, they can attempt to make changes at any time. Generally, there are a few ways in which an employer may try and make changes to an employee’s contract of employment. These are by:
· Receiving the employee’s express consent to the changes.
· Forcefully introducing the changes (called 'unilateral change of contract').
· Giving the employee notice to terminate their current contract and then offer them immediate re-engagement under a new contract that contains the new terms.
So the contract will be binding but can still be subject to any future plans on the employer to try and amend your existing terms and conditions. If they do so then you will have certain rights to challenge them.
This is your basic legal position. I have more detailed advice for you in terms of the rights you have to challenge potential future changes to your terms, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
