Unfortunately I cannot help as I am on my xmas break
The issue seems to be these days that if you have a sick note you cannot work - even if you want to. One of my team had a wee op on his nose - nothing much but because it was a full anasthetic he got a two week sick note. He asked if he could come in to clear up some work and was told that he would have to have a "fit note" or wait until his sick note had expired. We refused to let a man come into work even though he wanted to and was capable.I bust my ribs last year and went to the docs who reached straight for the sick notes - I declined the offer and went back to work after two days off..
Our employer does allow people into work . Their fit note can say they can do restricted duties but nothing that involves x and y. Works well.
