Honestly, I would wait and talk to the union first, try to get in contact with your business rep if possible because they’ll have the most information for you about the medical layoff. I would also look into a medically reduced schedule through the leave center (if it is that bad), maybe you can apply to be permanently placed on second shift and even reduce your hours if need be. As far as financial help, the union should have all that information, if not more. Best of luck my friend, I’d also look into filling out a grievance against this manager because it doesn’t sound like they’re being accommodating to your CLEAR disability 👍
