Owners Demand For Coworkers To Pay For Other Coworkers Overtime If They Cover Their Shift.

Location: Washington state, I work at a small buisness, specifically a burger restaurant. Ive been working for this buisness for a year now, within that time I've witnessed or experienced many sketchy things to say the least. We do not get paid time off like most restaurants and must find coverage if we cant work our shift or must request the day off 2 weeks in advanced. Tonight an employee got a shift approved for coverage. Employee B will cover Employee A's shift. When the info was sent in the group chat our Owner said that Employee A must work his shift or have to pay for the overtime of Employee B. This is not the first time this has happened, that I have witnessed. The last time was the exact same situation except Employee A was 17. In both situations the employees did not pay for the overtime and just worked their shift and had the coverage approved by a manager beforehand. In the past the buisness has had issues with laws regarding minors as well. I believe I have screenshots of the messages of both incidents. There has also been countless safety issues that should have been immediately fixed such as our kids juice cans being directly underneath the hamburger patties which later I discovered that most of the cans had been covered in blood.

The problem is I dont know if it is even worth reporting or anything. This is my first job and I would rather take the blame than employees who need the job to survive if I were the one to come forward with evidence from others. But I am worried that if I do get fired it would be hard to get jobs in the future. This isnt the only problem by any means but just the one I personally know about the most. Both the Owners have talked about how past employees have started "rumors" and how they have good lawyers who shut it down. In fact one of the owners either works or worked at a law firm which wouldnt that mean she knows what would be illegal and yet still continued? Should I report my employers or would that just cause more harm than good? What evidence can I really even collect of any of these claims?
