The following are contents of a job offer letter, except:

A job offer letter typically outlines the specifics of the position being offered, including basic information about the job, a clear articulation of duties and responsibilities, and any other job-specific details that are pertinent for the candidate to know. It can also affirm the nature of the employment relationship, such as stating that it is "at will," which makes it clear that either party can terminate the employment at any time for any lawful reason.

However, a job offer letter does not generally include explanations regarding grounds for termination and resignation. Instead, such matters are typically addressed in separate company policies or employee handbooks that outline the overall employment policies rather than in the individual offer letter itself. Including termination grounds in the offer letter could be seen as opening up potential liabilities or misunderstandings regarding employment expectations, which is why this kind of information is better suited for later communications.
