My daughter came up with a question? She works for a company that offers as much OT as needed. (As long as it gets done) It isn't hard work; answering phone; set up appointments; posting; waiting on customers buying parts;etc. She might work 60+ hours a week. Her question is " how many hours do you have to work and start losing money?" In other words you are paying more in taxes than you are bringing home. She called it 60-40. Seems like it was 47.5 hours when I was working. Anybody got a clue?
