The Occupational Safety and Health Administration (OSHA) investigated an Orlando Circle K location following the non-fatal shooting of a night-shift employee. 

OSHA cited Circle K Stores Inc. with one serious violation for failing to provide a place of employment free from recognized hazards likely to cause death or serious physical harm. A review of OSHA investigations of Circle K locations since 2014 finds five workers suffered fatal gunshot injuries at two locations in Texas in August 2021 and December 2018, Georgia in September 2019, Florida in June 2016 and Alabama in December 2015. The majority of these incidents took place in the evening or overnight hours.

Deterrents to help late-night retailers protect employees from workplace violence include interior and exterior security cameras, cash register barriers or enclosures, a drop safe or cash management device, proper lighting inside and outside the store and signage explaining the register holds $50 or less. The National Institute for Occupational Safety and Health cites robbery-related homicides and assaults as the leading cause of death for retail workers. In 2019, the rate of deadly workplace violence among convenience store workers was 14 times higher than the overall rate for private industry workers.

OSHA offers recommendations for workplace violence prevention programs in late-night retail establishments with employers’ tips to design and implement programs to prevent workplace violence.
