Job offer letters, also known as employment offers, are formal documents that outline the terms and conditions of a position, including salary, benefits, hours, job duties, and other details. They typically include information about the company and its mission, as well as a description of the job duties and expectations. A job offer letter should also include a deadline for the candidate to accept or decline the offer. The letter may also contain additional information such as the name of their supervisor, start date, and other relevant details. The offer letter should be signed by both the employer and the employee.
