I need information on temporary layoff and what my rights is.?

I was informed at work about 3 and a half weeks ago that because of work being quiet i had to be temporary laid off and recieved a letter saying that much and my p45. I was under the understanding it would only be for a week but how wrong was i. The 1st week of my lay off i received �111 pounds but since then nothing. I have been with my current employer for little over 3 years and have no contract so it was never informed about lay offs or that it might happen. Since then i have send my boss a text to ask about work and he said that they are trying to pull jobs forward.....that was 2 weeks ago. I need help as cant afford to wait around anymore and want to do something about this. Any help or advice would be much appreciated.
