Unemployment insurance is a form of insurance in US that pays you if you lose your job due to layoffs and other conditions. It is paid by you so it is not “welfare.” It is managed by each state independently and has some rules. For example, if you lose you job today and “don’t claim” unemployment insurance for two weeks, those two weeks are not paid out to you (this is in Texas). Every week, you must show that you are “actively” looking for a job. You may lose the benefit if you are not, or if a job is available but you decide not to take it. You must report on your efforts to find a job (interviews etc), and must attend some state class about looking for work.
Most states’ unemployment insurance covers up to a maximum benefit per week, and a maximum number of weeks. When I lost my job once, I was paid $325 per week.
