Got the call from the LA personal Department and the lady told me I will receive the offer letter in 2 days and paperwork to fill-up. "Thank you for your offer, which I would like to accept.You can state that you accept the compensation items, such as salary, benefits, paid time off, and the start date. California laws say that, in general, you are not required to give your employers two weeks notice – or any notice – prior to quitting or leaving a job. The answer to your question, regarding whether you can back out of the Offer Letter, is likely "Yes. First, make sure you put in your twoweek notice with your current job and notify any other employers you were in the hiring process with. Unfortunately I must work my two weeks notice. My current employer has always been good to me and I wish to return the favor. Generally, this letter should be sent within the time of few days, only once you have received your employee's resignation letter! No, employers don't need to keep employees on for the full twoweek period once they receive a resignation letter.
