A woman in work was married a year ago on Sunday. Her husband surprised her with tickets to New York for St Patrick's day and a few days before and after (I'm in Ireland). The problem is that because it's a holiday time here, a number of staff have already booked days off that week and I really can't afford to let anyone else go without other staff being asked to work overtime (which will eat into the overtime budget.)
The same thing happened for her 30th birthday last year. He booked a surprise holiday to Paris and I got one day's notice that she would need three days off (and we had a large conference during one of those days so I had to 'borrow' someone from another team to cover).
I hate to say no as the tickets have been bought and she's very excited. But on the other hand I'm getting a bit fed up of these surprises that put me and colleagues in a difficult situation.
WIBU to say that due to shortage of staff it's just not possible to approve her leave, and come across as a complete cow.
