I need a bit of advice. I've been working as a temp for over a year in the same role. Due to the working environment, alongside other issues I've been signed off work for a month with anxiety and depression. I've only taken one day off sick so far and contacted my GP who signed me off and prescribed some anti depressants. My issue is that after receiving the sick note, they called me to suggest that I resign as it's in my best interest. I was shocked because I had already spoken with them earlier in the day and wasn't expecting for them to suggest that. They've said that the organisation I'm working for can't guarantee they can keep my role open as they are short staffed. They said they would give me a few days to consider whether I'm going to hand my notice in.
I called ACAS and they just said I don't need to resign, and could put in a grievance in with the agency. Whilst this is sage advice, I doubt the agency are going to help me find another job if I lodge a grievance.
My concern is that if I hand my notice in I won't be eligible for UC if I can't find other work. I feel under so much additional pressure which is not helping my mental health. What do I do? The agency have also emailed with another role in the same organisation, asking if I want to be put forward for it. I've barely been sleeping recently due to stress so I'm a bit wired.
