Out of all industries, construction is considered to be one of the most dangerous for workers and for the general public. In fact, the United States Occupational Safety and Health Administration attributes around 20 percent of all fatal workplace injuries to the construction injuries. Nonfatal injuries are also much more common among construction workers. The general public is, in turn, often put at risk because of the accidents that cause workplace injuries and fatalities to workers. To reduce the occurrence and risks to all, one Canadian study suggests the use of union workers.
