In 2015, a 25-year-old flooring installer named Roendy Granillo collapsed and died of heat stroke on a construction job in Melissa, a small town northeast of Dallas, after his family said he was denied a water break.

They carried his story to Dallas City Hall, and the council passed an ordinance on a 10-5 vote, guaranteeing construction workers a 10-minute rest break every four hours.

Austin had passed a similar rule in 2010.
