Electrical line workers work all kinds of hours in very challenging conditions to keep electricity flowing to our homes and businesses. It's traditionally been a very male occupation but that's changing as more women break into the industry.

We speak to Columbia’s first ever intake of female apprentice line workers about their intensive training experience, and Rosa Vasquez – one of the first women to do the job in Texas in 1978. We also head to Pakistan where there are currently no women in this line of work.
