Many thanks for your patience. I tried calling but you were busy so will try later. In the meantime I will give you brief outline of your rights. In the circumstances the only way to take the matter further (apart from an internal grievance) is to resign and claim constructive dismissal in the tribunal. You cannot just make a standalone claim for this there, so to be able to claim you would have to leave your job first.
Constructive dismissal occurs when the following two elements are present:
· Serious breach of contract by the employer; and
· An acceptance of that breach by the employee, who in turn treats the contract of employment as at an end. The employee must act in response to the breach and must not delay any action too long.
A common breach by the employer occurs when it, or its employees, have broken the implied contractual term of trust and confidence. The conduct relied on could be a single act, or a series of less serious acts over a period of time, which together could be treated as serious enough (usually culminating in the 'last straw' scenario).
The affected employee would initially be expected to raise a formal grievance in order to officially bring their concerns to the employer's attention and give them an opportunity to try and resolve them. If the issues are so bad that the employee can't even face raising a grievance and going through the process, or if a grievance has been raised but has been unsuccessful, then they can consider resigning straight away.
If resignation appears to be the only option, it must be done without unreasonable delay so as not to give an impression that the employer's breach had been accepted. Any resignation would normally be with immediate effect and without providing any notice period. It is advisable to resign in writing, stating the reasons for the resignation and that this is being treated as constructive dismissal.
Following the resignation, the option of pursuing a claim for constructive dismissal exists. This is only available to employees who have at least 2 years' continuous service. There is a time limit of 3 months from the date of resignation to submit a claim in the employment tribunal. I note you said you have been there for 2 years so you must be confident that you have more than 2 years at the time of resignation to be able to take it further. Also the time limit is 3 months from date of termination of employment, not 3 months from date of incident.
