Tulsa police have arrested a disgruntled Walmart worker in Oklahoma who they say threatened to shoot another store employee before responding officers found her sitting in a car outside with a loaded handgun, according to authorities.

The suspect, identified as Adrienne Edwards, allegedly made the threats after supervisors disciplined her for being "mouthy" during a shift last week, Tulsa police said in a statement.

Multiple witnesses told police they overheard the threats, which allegedly involved remarks about shooting a colleague.

Police said officers arrived to find Edwards in her car near the store's front door.

The incident comes as the shopping chain and other retailers prepare for the busy holiday season – which is already known in the industry for increased stress, retail theft and even violence.

According to the National Institute for Occupational Safety and Health (NIOSH), retail workers are among the most exposed to workplace violence – especially convenience stores and gas stations where alcohol is sold. As a result, the Department of Labor advises taking all threats seriously.

The danger is largely driven by robbery crimes, however there have been deadly exceptions.
