Sally Citizen is excited to accept a job offer from Atwill Incorporated. She has spoken to her new manager and is told she will receive stock options in 2 years and an annual salary of $100k. She signs her offer letter which is silent on the issue of whether Sally is an at-will employee but states that she will receive stock options in 2 years and that her annual salary is $100k. On the first day of employment Sally signs a handbook as is required of all employees. This handbook is also silent on the at-will nature of her employment but does state that policies can be changed at any time for any reason/no reason and outlines the company's disciplinary process which includes termination. Is Sally and at-will employee? Does Sally have a valid employment contract? What should have been changed (included / not included) in her offer letter and handbook to clarify the situation.
