Since the first federal minimum wage went into effect in 1938, there have been people calling for an increase. Recently, there has been a push for a $15 hourly minimum wage at the federal level, as well as within various state and municipalities. Many of these calls for minimum wage hike have been led by, and funded by, unions. One in particular, Raise the Wage, called for a $15.25 minimum wage in Los Angeles and was funded by unions, including AFL-CIO.
