I think that they are allowed to do this so there is nothing i can do.
I wanted to take one week time owing (they owe me over 30 hours from working late/no breaks etc and they wont pay me for this)
2 weeks A/L then start mat leave around Jan 7th.
My manger has told me that i am not allowed any leave over Christmas and new year week so i have to work it or take mat leave.
I am taking 12 months off which means if i go before Christmas i will be stung for working all of Christmas next year as they wont allow me to take any over next Christams either and tag it on the end of my mat leave.
I will be 37 weeks when i finish.
I am in a very poor physical state now
going to be much worse then.
I had everything planned out so well. All for nothing it seems.
