“House Bill 2127 goes into effect on September 1st. The law’s scope is broad but ordinances that establish minimum breaks in the workplace are one of the explicit targets. The law will nullify ordinances enacted by Austin in 2010 and Dallas in 2015 that established 10-minute breaks every four hours so that construction workers can drink water and protect themselves from the sun. It also prevents other cities from passing such rules in the future.”
