OP is there anything different about you?
Different colour, race, religion etc?
Many years ago - I thought I worked in a nice workplace, full of nice people.
One girl was getting married.
Found out a bit later on that she had a works hen do and everyone was invited, even the men!
Except for me and 2 other women.
I am Indian, the other 2 women were Chinese and African. Really obvious why we weren't invited.
It explained why the atmosphere was tense before and after that party at work.
Even my manager couldn't look at us.
We found out a few weeks later and it explained why everyone was acting strange and the other room would suddenly go quiet if one of us suddenly walked in.
Also looking back I realised we were segregated.
We were given the crappiest jobs and put in a separate room, despite being the only university educated ones and the only ones doing the professional qualifications.
There was only one other white woman with us in that room but, she had to sit in that room as it was near a particular port that she needed for her banking stuff. She was invited to the hen do.
If they really felt that nothing was wrong they would've been open about it.
Now it is so clear they really couldn't tolerate us - for what? Not being white!
Happy to take lifts home and money for the wedding collection etc - not too foreign for that!
