This question already has an answer here:
I am a new graduate in engineering. I'm based in the UK and recently applied and was accepted to a job. I've signed the contract and the job begins in a month or two. However, I've been told to apply for multiple other jobs in case the offer is rescinded. My situation is that the job required a medical and I am concerned the company could rescind due to my disclosure of said medical condition.
I've been advised by relatives and others to keep looking and applying to see if I can do better/ as a backup, ideally outside of my field (elec engineering). I am concerned about the ethics of the thing, and I also feel I do not want to go through the whole job hunt, research, apply process again. Could someone please advise on my situation, it would be really appreciated?
