Many thanks for your patience. The starting point is that as someone who has worked there for less than 2 years, you generally do not have many rights, especially not the tight to claim for constructive dismissal (which would have been the usual claim to make in these circumstances).
However, if you have been treated detrimentally because of your religion, then that could amount to discrimination, for which the 2 year limit does not apply. So you could consider resigning and making a claim for religious belief discrimination in the Employment Tribunal.
Before a person can make a claim in the employment tribunal, they would be required to participate in mandatory early conciliation through the Advisory Conciliation and Arbitration Service (ACAS).
The purpose of this process is to allow ACAS to mediate between the claimant and respondent to agree on an out of court settlement in order to avoid the need for legal action in tribunal. The respondent does not have to engage in these discussions, or if they do and the talks are unsuccessful, the claimant will be issued with a certificate allowing them to make a claim.
However, if a settlement is reached, the claimant would agree not to proceed with the claim in return for the agreed financial settlement. Other terms can also be agreed as part of the settlement, such as an agreed reference.
To initiate the conciliation procedure ACAS can be contacted online by filling in the following form (https://ec.acas.org.uk/Submission/SingleClaimantPage), or by phone on 0300 123 1100.
If the conciliation process was not successful and you then wanted to make a formal claim in tribunal, you can do so here:
