Employment Offer Letter Instructions. Send the offer letter.It is a pleasure to inform you that the Department of ____ has recommended your appointment at the rank of ____, effective ____. Got offered one job, accepted, realized it wasn't full-time, took a different job offer starting the following week. Unemployment thinks they overpaid me. The offer letter represents what the employer is choosing to offer for the position. It is therefore wildly inappropriate for you to modify it. If you send a letter accepting the offer, you indicate your willingness to work, but it is not really binding in the sense you seem to be thinking of. There is very little legal binding in a job offer. The worker needs to sign the job offer to indicate their acceptance.
