The reason I didn't say something at the time is because I have been through a similar process previously whilst a permanent employee, it was highly traumatic (most women don't do anything), I was successful in keeping my job / removing the offending male but it wasn't worth it for the cost to me. I was traumatised by what was happening and that it was happening again. I have an official meeting tomorrow.
I have a certain amount of evidence from what happened, I just didn't realise I would be measured on the 'performance' issues that were stated (which actually were quite ridiculously minor). I asked this question as I was querying whether supposed 'poor performance' when caused by / in line with improper occurrences held any weight in law.
Thank you for your responses. I am not expecting to be reinstated, I wouldn't want to go back into that environment. I have already considered whether the harassment was actually unlawful (I believe it was) and as it only happened a few weeks ago I understand I am still within time limits.
Thank you to others that have responded.
