Hello there I would like advice as to whether I am being realistic. I am a head of department. I had a heart attack 7 months ago and have been awaiting treatment since. This means I have been off work, with a understanding school. I have had external cardioversion to correct arrhythmia and in three and a half weeks I have a triple heart bypass to undergo. My question is, am I being realistic in planning to return to teaching after convalescence?
