I left a part-time position with real short notice to take a full time one. My former employers are saying they're not going to pay me for my last two weeks of work because I didn't give the amount of notice it said I needed to in my contract. I've looked at my contract, and it says nothing about pay being withheld in a situation like this. What rights do I have in a situation like this, and how can I collect what's owed to me? .
