(CNN) - The Service Employees International Union is planning a new television ad to prod the administration to help derail dramatic proposed pay cuts for California's health care workers.
The spot, which will begin airing later this week, was first announced over Twitter on Monday by union president Andy Stern.
California Gov. Arnold Schwarzenegger has called for the cuts, which would lower health care workers' wages to around $8 an hour, to help get the state's spending under budget. The White House had said the move could cost the state millions in health care-linked stimulus funding - but has since appeared to back off that threat, say union leaders.
The new ad will focus on the story of Pauline Beck, a home health aide candidate Obama famously joined for a day to highlight the challenges facing the nation's service workers. It is slated to begin airing the same day the president visits Los Angeles for a Democratic fundraiser.
