In 2003, Weyco, Inc., gave employees a 15-month advance warning of a new policy that went into effect on January 1, 2005. The policy prohibited employees from smoking, on or off the job. The company provided smoking cessation programs to employees to help them quit before the policy went into effect, but employees still complained that this policy violated their privacy rights. Can Weyco legally forbid their employees from smoking when they are not at work?
