were you issued with a new contract setting out your days of work?
Ok have the hours / days ever changed as a result of the review?
Ok but it was agreed that you would not have to work Fridays (even though this is not set out in the contract).
Sorry was it specifically agreed that you would not work Friday or not. I'm not clear from your response.
Ok thanks, XXXXX XXXXX is not entitled to just require you to change your day. Whilst they state that the contract is subject to termly review the effect of a change in contract under the Flexible Working Regulations is that the change is permanent. This means that if you do not agree to the change it would amount to a unilateral variation of your terms and conditions for the change in day to be imposed.
You can raise a greivance about this to your employer. Ultimately the employer could give you notice (under the contract) that the day would need to be changed, but the employer would have to act reasonably in doing so.
The fact that someone else is reducing their hours should not result in you having to change your days in this way. You can argue it amounts to a breach of trust and confidence.
You have not stated if the other person has childcare issues, potentially if they do not you can argue a decision to change your days is discriminatory.
If you have any further questions please do ask.
No he is not right. You do not have less rights.
As you have reduced your hours and your day off is Friday this is what you are contractually entitled to.
Your employer does not have the automatic right to change this.
As I have stated above you should raise a grievance.
No problem, I do hope you can resolve this. It is likely that your employer does not understand the legal position correctly.
Please do come back to me if you have any further questions and please take the time to rate my answer. Thank you and all the best.
