Good evening Sue,
I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today. I have represented nurses in actions against hospitals and nursing facilities on many occasions, and my wife is a hospital nurse, so I understand how the health care employment situation is, and in today's employment market, just how easy it is for an experienced nurse to find full time employment.
If you are not being relieved from your job duties, then it is unreasonable that you clock out during the period of time that would traditionally be your mandated meal break.
However, if you are relieved for lunch and have the opportunity to leave the facility, and only are potentially on call during that time to be called back to work, then they may demand that you clock out when leaving for lunch. If you are called back in that situation, you will just have to punch back in and go back to work. They will have to pay you for the time that you were off for a portion of the meal break that day.
However, under CA law, if you are required by your employer to remain at your facility during the meal period, then you must be paid for each meal period you take, and it is inappropriate, and accomplishes nothing for the employer to have you clock out and back in again---however, it is not illegal to do so, and the time clocked out cannot be left unpaid, even if you really get the full 30 minutes off occasionally.
Under CA law you are also entitled to a 10 minute break every 4 hours on shift, for which you do not have to clock out, and which must be paid for.
Please keep in mind that, even though you have already paid your deposit money over to JustAnswer, until you rate me highly for my service, I will not be paid for having assisted you with your questions.
If you have additional questions, you may of course reply back to me and I will be happy to continue to assist you further until your questions have been answered to your satisfaction.
I wish you the best in your future.
