I was meant to reply last night and fell asleep sorry!
In the short term I plan to stay off, I've noticed even little things in the house I keep putting off despite all the best intentions of doing. Even though a day or two and I could have everything sorted, before I know it , it's night time. Almost like I'm mentally not wanting to take it on, probably a side effect of my job taking its toll. Plus speaking to people in work and checking my emails , nothing has changed since I went off. Same pressures , same under staffed and nothing has been done to protect those who are in despite knowing for a fact they have lost someone to stress.
I think longer term , your suggestion is exactly what I need, it's actually really helpful. It puts me in a stronger position my side as well as I have the means to do it (equipment) and them refusing me can lead to stress again given the circumstances. If they over rule a doctor advice , then if they were to take it further with me , that's a pretty good defence on my end! So I will go ahead with that in mind. Once everything outside of work is sorted and I feel ready to start up again, I will ask about that.
Worst case scenario is that if they refuse, I go back off with stress and look for a new job , if at the very least I can sort out my side school wise.
