State law prohibits individuals from carrying or wearing a dangerous weapon of any kind (including knives, switchblades, stars, and nunchakus) concealed on or about his or her person (MD Code, Criminal Law, Sec. 4-101(c)(1)).
The owner of a business or property may carry a concealed handgun within the confines of the business establishment during the course of employment. The owner may designate a supervisory employee who is licensed to carry a gun to carry a concealed gun in the facility while the owner is absent from the facility (MD Code, Criminal Law, Sec. 4-203). A person may not transport or store a handgun, whether concealed or in the open, in any parking lot used by the public or on school property unless the person is a law enforcement officer or member of the active-duty armed forces.
Employers are liable when they fail to protect an employee who has a court order against the employee's domestic partner from contacting him or her at work (Gantt v. Security USA, Inc., and VSI, Inc., 356 F.3d 547 (CA-4, 1/23/04)). The existence of a protective order should warn employers not only of the danger to the specific individual but also of the potential liability of harm to co-workers caused by allowing the employee's partner into the workplace.
