A Calgary construction worker who became a YouTube sensation when he made a joke out of high rise construction safety has been terminated by his employer.

Last week, the president and CEO of Skyway Canada, Gary Carey, confirmed that, after an internal investigation of the incident, one employee was fired.

The video, which was posted on YouTube in October 2009, shows a number of construction workers as they worked from scaffolding on the 29th storey of a condo development under construction. One worker could be seen tossing a metal clamp and passing a co-worker a metal rod. The worker who tossed the tool was fired for violating company policies. Another worker was suspended, but allowed to return to work after the investigation, after it was determined that he wasn’t involved in the prank, and had actually voiced his objections to the other workers. A third worker involved in the video is no longer with the company.

When the video was discovered online, it was passed to company and government officials, all of whom saw the behaviour as offensive, especially since it came approximately two months after the tragic death of three-year-old Michelle Krsek, who was killed by metal roofing material that fell from a downtown Calgary high rise construction site.

Skyway still has to submit a report to Occupational Health and Safety officials.
