Many thanks for your patience. Sexual harassment at work is a form of discrimination which is unlawful. The issue is proving what actually happened, because often there would be no independent witnesses and it would be your word against the harasser’s. So it does mean that making a claim can be risky because a court or tribunal may not accept your version of the story.
In any event, under general employment principles and health and safety regulations the employer has to look after your welfare and safety at work. If they know that there are issues which pose a risk to these and have failed to adequately deal with them, it could amount to a breach of trust and confidence. This could allow you to potentially resign and claim constructive dismissal.
An alternative way out is to approach the employer on a 'without prejudice' basis (i.e. off the record) to try and discuss the possibility of leaving under a settlement agreement. Under a settlement agreement, the employee gets compensated for leaving the company and in return promises not to make any claims against the employer in the future. It is essentially a clean break, although the employer does not have to agree to it so it will be subject to negotiation. In any event, there is nothing to lose by raising this possibility with them because you cannot be treated detrimentally for suggesting it and it would not be used against you.
If your suggestion is rejected and there is no apparent resolution on the horizon, you could consider taking action for harassment against the individual. You can do this either as a sexual discrimination claim in the employment tribunal or a harassment claim in the county court.
This is your basic legal position. I have more detailed advice for you in terms of the steps you need to take to progress this further, 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
