Ask employees if they've witnessed workplace violence in the last five years, and one in four are likely to confirm they have. Meanwhile, 12% may acknowledge they were the target of such action, according to a recent survey of 1,000 U.S. employees by compliance training solutions provider Traliant.

And employees want their organizations to do more about violence at places of business. Ninety percent of survey participants believe other states should follow the lead of California, where a new workplace violence law takes effect on July 1. California Senate Bill 553 requires virtually all employers to establish, implement and maintain an effective workplace violence prevention plan that is enforceable by the state safety and health agency.

Since last year, more than 100 bills aimed at reducing workplace violence have been introduced in 27 states, with 11 states enacting these measures, according to a LexisNexis State Net data report. In states like Connecticut, Texas and New Hampshire, the adopted legislation only applies to healthcare settings. In contrast, other states like Utah have passed workplace violence bills that focus on delivering particular tools to employers, such as getting a protective order on behalf of an employee. New York, meanwhile, passed a workforce violence prevention law to protect retail workers. California is the first state whose anti-workplace violence law applies to employers across industries.
