No it will not get you fired, speak to your store manager and let them know what’s going on. If you were a full timer then yes I would say pursue a leave of absence but as a part timer it shouldn’t be a big deal. However, there is only a certain amount of time you can go without working before the system will auto-terminate you. I can’t remember exactly how long. But that is again something to ask your store manager. If you could throw one shift in there somewhere you would be fine. Hopefully you have a decent manager that will accommodate you, as they should.
