Redline Courier Service will layoff about 80 percent of its workforce this spring, including at its Chatsworth facility. The Mission Hills delivery service notified the state Employment Development Department on March 9 that it would permanently eliminate about 169 positions, effective May 9. That number includes 46 employees – 44 delivery drivers and two dispatchers – from its Chatsworth location. The others are in Los Angeles, Hawthorne and Chino. Redline was started in about 1997 and operates round the clock, every day of the year. It serves the architectural, engineering, legal, accounting, medical and fashion industries.
