Thanks for your patience. it would appear that you may be the victim of bullying and/or general unfair treatment. Whilst workers do have rights in relation to this, many of these rights can be limited due to the worker’s length of service. This will be a problem here unfortunately.
In cases of bullying or unfair treatment the only legal remedy you would have is under protection against unfair dismissal or constructive dismissal. So it is where the employer either dismisses you because of this or you are forced to resign as a result.
The issue for you is that if you have been continuously employed at your place of work for less than 2 years then your employment rights will unfortunately be somewhat limited. Most importantly, you will not be protected against unfair dismissal or constructive dismissal. This means that your employer can dismiss you or force you to leave for more or less any reason, and without following a fair procedure, as long as their decision is not based on discriminatory grounds (i.e. because of gender, race, religion, age, a disability, sexual orientation, etc.) or because you were trying to assert any of your statutory rights (e.g. requesting maternity/paternity leave, etc.).
So whilst you are able to pursue this internally via a formal grievance, if that does not help and the issues continue, then your only other option would have been to resign and claim constructive dismissal, which unfortunately you cannot do due to not having the required length of service. Of course if there were discriminatory grounds for this treatment that could change things but some evidence of that would be required.
This is your basic legal position. I have more detailed advice for you in terms of the rights you have to challenge this in the event there was discrimination, 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
