I am SO angry that I am on the verge of tears. Sorry if this gets a bit long/ranty 
I work 8 hours per week in a shop. The shop trades from 9-9pm during the week. My days tend to alternate between wednesday and friday and despite my persistent asking, I am usually only told of my shift patterns with a couple of weeks notice (but that is another thread...) My manager keeps a diary that we can all write dates that we can't work for whatever reasons, exams/holiday/whatever. The general culture there is if you give enough advance notice it is not a problem to change your working days. I checked with my manager in april if I could pop a date down for October that I would be away (next friday). She said that was fine and I popped the date down.
Fast forward to now and I went back to work last wednesday after a two weeks annual leave and she has put me down to work next friday, when I told her I would be away. She huffed and puffed and I pointed out that it had been in her diary since april and she went "the diary has gone missing" So she'slost her diary and obviously not remembered. I have paid £130 for train and accommodation to go to Manchester so I told her as much and that I couldn't do it. She said she'd put me in for wednesday instead (which is what she should have done anyway) and she'd get someone else to do friday. Turns out no-one else can do it so she's just sent me a really shitty Facebook message saying that now she'd got to do it and it had messed up her plans, I should have booked it off as holiday (even though I don't do every friday) and that she'd speak to me next week. What the fuck?!
I replied saying that I don't think it is fair that I should book holiday for a day I don't always work and even more so because it had been OK'd over six months ago! I said that if she had wanted me to book it as leave I would have done but when I brought it up initially it was said that it was enough notice for someone else to work instead of me.
I think that giving notice in april for a date in october is far enough in advance for her to sort her shit out. If she loses her diary, that isn't anyone else's fault. She is a scatty person and she has done this sort of thing before (cocked shifts up and got angry when the onus has fallen on her to sort it) but the onus isn't on me to sort this, is it?
I am so angry with her. She is trying to intimidate me into working it.I know what's coming next; threat of conversation with the area manager. After the shite week I've had (and she knows about it) I am insulted that she has invaded my personal time via fucking Facebook to try and intimidate me. -fume-
Sorry for rant, but I needed it!
