One's LPR status does not end with the expiration of the card. As a result, the work authorization is still valid, and there is no basis to terminate an employee ONLY for that reason. You ask how the employer would know about the expiration of the card. The I-9 the employee filled out upon hiring would have the expiration date of the card, and the employer would ask for the updated card.
