Is it legal for a fast food establishment to force employees to pay full price foe their meals? (New Jersey)

I came in to work today after being off yesterday and have been informed that because of missing product EVERYONE has to pay full price for meals. I have never, nor has any of the regular staff to my knowledge been disciplined once when it comes to missing product. We're not paid much and this seems incredibly immoral in an industry where all of the employees are struggling. Am I the one who is wrong here?
