If I was sucker punched at work by a coworker I think I would have a hard time moving forward with that person. I might be able to put it aside for a time but payback would be coming. This is a bad situation. I mean that is a criminal charge.
I don’t know what you do for a living, but these players work in a business which welcomes acts that would typically lead to criminal charges if they weren’t on the field.
A sucker punch is certainly crossing a line. But physical fights and altercations happen at practices all the time. Comparing it to a normal work environment doesn’t work.
