Kingcanute - I am not talking about any possible future fall out I'd rather base my argument around the here and now and the facts.
She had already lost her job, the DM didn't get her sacked. She had already posted about it on an internet chat room that anybody, including her former employers, can see - the DM didn't make her do that. The DM actually removed details of her occupation -she posted that herself in the original.
Let's say her ex boss did read the DM column and suspect it was her. he cannot prove it, he can only ever suspect. and it cannot have any bearing on a tribunal. If she was sacked for being pregnant then she has been sacked unfairly - the thread is irrelevant to the tribunal, the facts and its outcome.
When the sacked woman originally posted it was under a new name: 'sackedforebeingpregnant' or whatever it was...if the ex boss searched under that name he would find one post and one post only. he can never know for certain this was his employee.
