LOS ANGELES (AP) — Squeezed by state budgets cutbacks, the Los Angeles County court system is launching massive job layoffs, pay cuts, and transfers Friday.Cutbacks will affect 431 court employees and 56 courtrooms throughout the nation's largest superior court system.Presiding Judge Lee Smalley Edmons says longtime employees are being laid off in the quest to save $30 million. She notes that earlier reductions already saved $70 million, but more cuts in state support for trial courts are scheduled for the next fiscal year.The plan calls for laying off 157 people while hundreds more will be given lower-level positions, reduced to part-time work or transferred to new jobs because their old ones have been eliminated.Targeted employees will not be identified until they are notified Friday morning, according to a court spokeswoman.
