Construction workers and their supporters are calling for changes in their line of work after a new study points out some alarming figures about the dangers on the job. 

According to the New York Committee for Occupational Safety and Health, half of construction deaths state-wide are from falls. Among them, about 79 percent happen at non-union sites. Union workers say that's because non-union employees don't get the same type of safety training.

Their family members say that's got to stop.

"He always was working hard for my family. He don't take nothing from another person. Everything he has is because he works. And now, we want justice," said Monica Velazques, whose father died in a construction accident.

Critics say they want the city to stop awarding contracts to repeat offenders. 

They also say they want more resources for site inspections.
