Thousands of union members and others participated in marches, rallies and picnics on Labor Day throughout the Los Angeles region and across the country on Monday, decrying actions by the Trump administration that they say weaken unions and harm workers while strengthening and emboldening major corporations and the wealthy. A White House proclamation Monday said President Trump's actions are "reversing decades of neglect and finally putting American Workers first" by rewriting tax laws and creating a better economic climate for businesses.
