Hello, I need some advice regarding legal aspects of accepting a job offer. Ages ago I applied for a job with company A, it is my dream job for all sorts of reasons. Got a conditional offer, which I signed and sent back. They are taking ages with all security checks and I have been applying for jobs in the meantime thinking that maybe something is wrong with my credit check etc. And I have just been offered another job at company B. I have no idea what to do. I have been told by company A that they need another week (!!!) to finish their checks. I want job A but if I don't get it, B is second best. Is that in any way illegal to accept job B if I signed conditional offer with company A? I know it is just horrible to accept job B and then just turn around and say "no thanks" should I get job A, but how does the legal side of things look? Job B is through an agency, not sure if it matters. I'd appreciate any advice.
