LMIA-Exempt Job Offer Expiration Date is before Work Permit expires

[sonny7878]

If your LMIA-exempt job offer paper has an end date that is earlier than the expiration of your work permit is that a problem? (It is over a year different, but the employer wants to keep us as long as possible and hoping we eventually get PR). Should the work permit be renewed before the end date stated on the job offer?
