Getting a transfer to another location

I work part time at Morrisons and when I go to uni, I wanna work at the
Morrisons there. Not only will this save the hassle of finding a new job and getting used to it, I am also sorted for the summer and holidays, as I will work at the Morrisons at home.

However, although outside the personnel office there is a big poster saying ''going to university? we want you to stay! hours to suit '' bla bla bla, the woman in personnel is generally being an awkward bast*rd about it.

I said that I would need a few weeks in the new city to adjust before I wanted to start work, however she said I would have to start straight away because you ''have to keep your contract going''. (even though, surely i will be getting a new one?)

She then said I could have it as holiday, then informed me I have no holiday left to use.

So now, I feel like I am being a pain for continually going into the office and trying to sort it, but I'm getting annoyed at the fake smiles and exasperated sighs.

I have half a mind to contact the store where my uni is and see what they say, because they are obviously more used to uni students and their situations.

Anyone else have similar experiences or wanna help me out?
