In the video, the employee is seen falling from the high-rise building after he seemingly jumped. Another person, who was some distance away from him atop the same building, appears to be beckoning for him not to.
Onlookers could also be heard screaming in reaction to the scary sight.
Reports are that about midday, security personnel were called to the scene of the incident, and the male employee was rushed to hospital.
Several workers were seen in groups seemingly discussing what had transpired, some in disbelief.
