Sorry for long thread title!
I work in a place where there are around 100 members of staff. We recently had celebration drinks & nibbles, cakes etc in the staff canteen at lunchtime.Think end of a big project etc.
I have a dietary condition, which my manager, plus the level above them and 3 senior managers have all been told about. Would your employer ensure there was at least a packet of biscuits, crackers or cake that was suitable for you? Just a basic supermarket 'Free from' product, nothing elaborate.
