Earlier this month, the Los Angeles City Council voted in favor a new law that would increase the city’s minimum wage from $9 to $15 an hour by the year 2020. Yet the Los Angeles Times reports that labor officials, who until now have been strong supporters of the wage hike, are asking for a last-minute change that would allow unions the freedom to collectively bargain for wages that are lower than the minimum.

“With a collective bargaining agreement, a business owner and the employees negotiate an agreement that works for them both,” Rusty Hicks, head of the Los Angeles County Federation of Labor, said in a statement. “This provision gives the parties the option, the freedom, to negotiate that agreement. And that is a good thing.”
