Since I mentioned this case recently and there was a discussion in the comments, I now add that it’s available online at the BAILII site.
The case summarizes the legal framework. It also contains some information on the claimant’s background and unhappy childhood. Examples of behaviour of others in the office are under nos. 70 ff. From no. 79 on, evidence from another woman who had experienced the same treatment as the claimant, and who referred to other cases too. From 107 on, information on problems with a male colleague.
This certainly sounds like a case that would have been interesting to hear, with the witnesses acting evasively, if one reads between the lines.
