The man was knocked unconscious and suffered a fractured orbital socket.
The attack happened back on Sept. 25 at J and A Hardware on Longwood Avenue.
Police said two suspects entered the store and started knocking items off the shelves. The worker confronted them, and a struggle spilled out onto the sidewalk.
Surveillance video shows one of the suspects come out of nowhere and kick the man in the chest, knocking him onto the pavement and causing him to hit his head.
The employee was rushed to NYC Health + Hospitals/Lincoln in serious but stable condition.
Investigators hope the newly released video will help track down men responsible.
