I am living in The Netherlands and recently left my last job due to a stressful work environment. However right before I left I became very sick and have been sick ever since. I have seen several doctors and they have all told me it is a stress-related condition caused by over-working. To clarify, I have been sick for just over three weeks now.
I am due to start my new job on December 1st (just over three weeks from now), however my doctor has told me that I may not be better by then, and I may only be able to return to work in January.
It is not certain that I won't be able to return to work by Dec. 1st however it is a possibility. How should I handle informing my new employer about this and what kind of a reaction might I expect?
My new employer is also very anxious for me to start work with them. The original plan was that I was going to start working for them already but Dec. 1st at the latest.
