Hi, A friend of mine works for a school. Before the school closes, the management sends a consent letter by email asking whether the employee wishes to continue. An acknowledgment was sent by email stating that she would continue, and the school closed for the holidays. During this period, one month's salary was paid. A better offer came during this period, and my friend accepted the offer. The school has not reopened yet, and she resigned from the school. Now the school is not willing to give the relieving letter and is about to send a show cause notice. She is willing to return the one-month leave salary that she received during the holidays. Please advise.
