Employers are grappling with new laws that bring guns closer to the office, reports the Wall Street Journal. Starbucks made headlines when its chief executive asked customers to keep guns out of company cafes. His appeal thrust the company into debates about the role of private business and public gun laws. Some 22 states limit property owners’ ability to ban firearms in vehicles in parking areas, says the Law Center to Prevent Gun Violence, a San Francisco-based gun-control advocacy group. Under most “Bring Your Gun to Work” laws, employers can keep firearms out of offices and factory floors, but they can’t ban weapons in the parking lot. Some companies are rewriting human-resources policies, training employees to detect early signs of employee aggression and considering extra security for tense situations like termination meetings. Law firms specializing in labor and employment say managers are bombarding them with questions about adapting to the new measures. Gun-rights advocates say such laws increase worker safety, and say that workers have a right to protect themselves during their commutes.
