Are there times when a good hiney whooping is necessary in order to make your point/correct an ongoing issue?

A guy my ex was familiar with had an issue with a dude on the job. Dude kept picking with him and would not let up or leave him alone. The guy went to management and H.R on several occasions. Since dude was friendly with the management, it fell on deaf eyes and ears, and the manager covered for dude when H.R checked into it. So after one workday too many of the guy getting hassled by this dude, he got off work one day and got revenge. He left the work site to keep from getting fired for fighting on premises, and waited near the job up the street for dude at a gas station. When dude stopped to get gas one day, the guy confronted him about all the shyt he does on the job site, a fight ensued and dude got his "hiney" beat down by the guy. The guy called the cops and waited for them, they took him on to jail, where he bonded out and reported for work the next day. When asked he claims the beat down of this dude was worth a trip to jail!
