I'm going to show you exactly how to send a follow up email after your interview if you've gotten no response, with examples and templates. I accepted a job offer through an email but I have not yet signed the contract.Is it possible to back out of the job. Civil Service review takes a while, but not six months. If you applied and it's been six months you didn't get it. Offer letters must be prepared to preserve at-will employment status unless the employer consciously decides otherwise. See Preserving At-Will Status. An Employment Offer Letter provides the employer with an opportunity to formally make an employment offer to an employee in a clear and concise fashion. As a general rule, an offer may be rescindedits just an offer, not a contractin fact, it may be withdrawn after acceptance too!
