I would like to thank you for this opportunity but regretfully must inform you, that I must withdraw myself from the offer of employment. Accepting a role and backing out after you've accepted is totally acceptable.It is all how you approach the discussion. Turning down a job offer after you already accepted it should be done gracefully. A sample letter declining a job offer after accepting it can take many forms, but as a rule you should keep it short, to the point, and completely professional. You should never stop the job search until you have a signed contract with zero contingencies. You can continue to apply and interview. "Unfortunately, I'm writing to rescind my job acceptance. " "I'm afraid I'll have to withdraw my job offer acceptance. Revoking an employment offer is not illegal in most cases, but the decision should be given a full legal review before contacting the candidate.
