Modified Right-to-Work Law

Colorado is a modified right-to-work state, with the most progressive labor law in the country. The Colorado Labor Peace Act requires two elections and approval from 75 percent of a company's workers before becoming unionized. 

Without the 75 percent approval, there can be no all-union agreement in the collective bargaining agreement, just as in a right-to-work state. In 2016, only 10.8 percent of Colorado’s workforce was a member of a union. A 2015 study showed that Colorado employment grew six times faster than unionized states from 2008-2014.
