Don't Forget to Ban Violent Behavior in Employee Handbook

Include in your employee handbook a ban against violent behavior by employees, to head off problems and put your employees on notice that this behavior won't be tolerated and that there will be serious consequences. Tell employees what's unacceptable, and draw a clear line that they may not cross without being fired. Include horseplay as part of prohibited conduct; it's employees' most common defense for unacceptable behavior.
