So sorry to hear this Snap.

Is there any way you can have a phased return with limited duties?

I had some health issues a couple of years ago and my doc certified me as 'fit within limits'. My employer involved me in consultations with occupational health to determine what those limits were. I had a six month gradual phase in.

Or maybe you are just not ready for work at all yet.

Can you talk to your doc to support you in this? My employers were terrified of a claim so were really co-operative...er, were acting as responsible employers
