I DON'T KNOW WHAT TO DO????
At work the other day, I witnessed one of our more seasoned(read older) employees bullying an employee about half their age. They were belittling the employee's work production, work ethic, and other characteristics. They were essentially raising their voice at every opportunity. They were finger pointing; even placing their hands on the younger employee from time to time.
The older employee wasn't even their supervisor!!!!!
What should I do?
Report the incident to HR or not get involved?
