I was signed off work for one month and I am due back next week. The reason I was off isn't on my sick note my GP put quite a flippant reason.
Should I tell my work the real reason which is I was exhausted due to iron deficiency and also I was waiting for tests results for a possible cancer reoccurrence.
I don't know if I should just give very little information during my return to work interview or if I should be as open as possible. I don't have a manager at the moment so it will be with another manager from a different department.
