If an employee resigns but does not provide proper notice, are there any options for an employer other than trying to sue them for wrongful resignation? Is it legal for a letter of employment to identify that if an employee chooses to resign any time after the probation period has ended, they must provide a notice period consistent with employment standards legislation, and if they don’t accrued vacation due to be paid out due to the resignation may be reduced by the legislated notice period, or balance of the period if a lesser notice was provided?
