Outsourcing is all about price and NOTHING about customer service.
I was outsourced at an airline and remember explaining to the "nodding donkeys" that it was imperative that they didn't do anything that would cause an aircraft to remain on the ground (AOG) unnecessarily. Altogether quite an uphill struggle. Fortunately, my (Indian) boss usually listened to me.
Agree with virtually all the above comments. Mainly nice people, but was quite glad when I retired.
