to be angry an disappointed at co worker

[Doha]

I am a leader of small team of 3 people and we usually get on petty well. However today l noticed that one of the team have put in her entire years holidays without discussing it with me and our other team member.
Not only that but she is off next week (leaves me no time to get cover) and she has taken 1 1/2 weeks of Easter holidays when we all have school aged children.
She left early again today (l only know because l was looking to discuss this with her) and it appears she does this on a regular basis, calling patients to come in ahead of their appointment times so she can skive off early,
I am off tomorrow and l was so angry l sent her an email saying l was not happy and copied the manager into it,
Now l hate confrontation and am stewing over everything, Feeling perhaps l was a bit unreasonable.
Don't think l will sleep tonight

I think I would be more concerned that she is calling Patients in so that she can go home earlier. If she is being paid to a certain time and not there for that time then it is fraudulent.

If you work for the NHS this is a big thing at the moment and most Hospital Trusts have fraud officers now working for them to prevent this from happening.
Over the last year a number of health care staff have lost their jobs because they have been fraudulent.

OK so if she did not follow procedure, her request for holiday has not yet been granted.

So when you see her you can either authorise or not depending on your level of cover and the reasons for her needing time off with short notice.

There has never been an issue before but this year as she has been given some "management" responsibility she seems to think she can change past proceedure and discuss with the admin manager her annual leave

Are you sure this isn't just a genuine misunderstanding on her part given that her role has changed slightly?

I can see why it would be annoying but it all sounds a bit of a storm in a teacup that can easily be sorted with a quiet word tbh.

Well, it sounds as though you have the authority to sort it out and you will. Her request might not be granted if it is not possible to arrange cover. If she has misunderstood the change to her role this will emerge and you will clarify things.

In my previous job we were a team of 6. Our manager would not let anyone book holidays full stop - as in she refused leave requests. Her justification was that she couldn't let other people book their dates until she had booked hers (meaning she got first dibs) and she couldn't book hers until her DH booked his. Her DH wouldn't book his because he didn't like going on holiday with her and the kids.

The upshot of this barminess was that we would arrive at about May (holiday year ran 1Oct to 30 Sept) with 6 people each with 6 weeks leave to take. In the end we took matters into our own hands as a team and told her that we were taking our holidays whether she liked it or not, we were adults and weren't about to leave the department without cover.

She had to back down but boy was she unhappy about it. She just didn't get that we couldn't fit 36 weeks of holiday into not much more than 20 weeks remaining of the holiday year without having more than one person off at a time owing to her bloody incompetence.

The moral of this is, if you're a manager, manage, because if you don't, someone will do it for you.
