At work yesterday I was involved in an incident with another member of staff where I asked why they're department couldn't do there own work which caused them to yell at me. After speaking to a manager about the situation and basically being told I was in the wrong and that it was ok for the other member of staff to yell at me because their position is more senior then mine, despite the fact i was visibly upset. The manager then asked me if i was just emotional because i'm pregnant, just wondered if this is considered an appropriate statement for a manager to make or whether it is discrimination.
