<human>: My Fiancé has applied for a new job last week, had the interview and it went fine. It was for a new store opening which is closer to home, has more hours to work and is a new start for her. 

Now she got the phonecall today saying that she got the job and her new boss says she has to start next week, she thought fine and went and told her current boss that she will be moving to a different store.

Her new boss went off on one, saying she can't leave the team as they will be short one person, saying that she will need to work 4 weeks notice (I thought this was odd as I thought working notice was only for when you leave the company completely, not when transferring her job). She was also saying that they need her there as people are off on holiday. 

I believe she is trying what she can to stop her from leaving and moving on to do better things. 

Now my Fiancé has phoned her area manager, which is her current boss's boss and even she agreed that it was just a transfer. 

Is there anything my fiance can say or do? Is her boss in the wrong for trying to deliberatly stop her from moving and making her feel guilty?

Can you give me the gist of the text in a nutshell?
<bot>: Fiancé's boss is trying to stop her from transferring to a different store within the same business, Fiancé feels helpless and doesn't know what to do, need help.
