Knowing how to accept a job offer is key. Thank the recruiter, review the offer and follow up with questions and a counter offer before accepting the offer.This letter serves as a pivotal tool in commencing your new role with confidence, setting forth clear expectations, and offering reassurance to the company. No. You either accept it, or you don't. If it isnt' acceptable, you need to have a conversation with them about what can be changed. Call or email the person who made you the written offer. I hope you took the better job. As a manager, if I was hiring you and you asked for my opinion, it would be to take the other job. A job offer acceptance letter formally tells your future employer that you have accepted the job offered to you. The short answer is yes, you can decline the offer.
