I spoke to my HR lady where I work she is very supportive. She spoke to ACAS who advise on all employment law and they said legally if you have a sick note you don’t have to use annual leave. She told me if it made me more comfortable to use 1 day annual leave for the day of procedure – then once I have had the procedure the sick note will cover me anyway as there is no possible way I could work for a week or so. Hope this helps xxx
