Massachusetts’ ban on workplace smoking has helped lower the number of people exposed to cancer-causing smoke on the job, but employees in lower-paid positions are significantly less likely to be protected, according to a study being released Monday.
The findings reveal that just 3 percent of nonsmokers in professional fields, such as software engineers, architects, teachers, doctors, and nurses, reported being exposed to a co-worker’s tobacco smoke. In contrast, 37 percent of trade workers who didn’t smoke, including auto body workers, locksmiths, cable TV installers, and heating and air conditioning mechanics, said a colleague lit up in their presence on the job.
Many other nonsmoking, blue-collar employees also reported high rates of exposure to secondhand smoke, including 23 percent of construction workers and 20 percent of transportation workers. Full story for BostonGlobe.com subscribers.
