<prompt> Human: Im a nurse and work 36 hours a week. I can pick up overtime shifts almost any day of the week and make twice my hourly wage for the shift. My coworkers tell me that its not worth it because you end up being taxed more. Ive heard that to make it worth it, you need to change your withholdings so you get taxed less. My argument to that was that if you didnt change your withholdings, you might get taxed more for that paycheck where you picked up double time, but you would get more of a refund or less to owe at the end of the year. One nurse said that the real issue is that you can put yourself in a higher tax bracket by picking up double time shifts, but my understanding is that if you only the amount over the tax bracket you surpassed is taxed at the higher percentage.Ive tried reading about tax brackets and withholdings online, but Im having trouble understanding it as it relates to my situation. Specific advice on my situation and simple explanations of how it all works would be much appreciated.  <response>: Dont tell your coworkers that theyre wrong so that you can keep picking up all the OT shifts!
