My husband is getting unemployment (about $1000) a month and now his former employer wants to hire him for part time work. They want to hire him through a temp. agency of which the agency wants him to fill out i9/w4 forms. The temp. agency also said that they do not get jobs from his field of work and the work he receives from his former employee will be the only work that he will get through their agency. We are really not sure how much work they are going to give him, but somewhere between $300-500 a month we think.

Questions
1) If he fills out a i9/w4 form and becomes a employee of the temp agency will he lose her unemployment?
2) If he does not lose his unemployment how much will unemployment take out?
3) If he goes over $1000 in a month will unemployment cease?
Thank You
