What to Do if a Co-worker Appears Dangerous

A story of a 40-year-old man recently accused of killing one person and injuring five at his former office can send even the most easy going office into a state of fear.

You never know if the sometimes-odd co-worker is harmless, or mentally ill with too many personal problems to count.

And while you don't want to be bothering the Human Resources Department with baseless complaints, it's better to be safe and a little too sensitive than to let things slide.

If you hear a co-worker discuss odd plans, such as saying goodbye to all of their friends, or make threats about shooting the boss because he or she didn't get a raise, then it's probably a good time to contact Human Resources or your immediate supervisor to let them deal with it.
