One of the major issues of contention between American Airlines and its mechanics – that has prevented reaching a contract agreement and contributed to the airline’s poor operational performance – is outsourcing. American outsources less work than other U.S. airlines.
However the trend is for high value work to be done in house, and lower value work to be outsourced. That’s a trend that union mechanics aren’t going to be able to escape. Legacy American Airlines mechanics are in their mid-50s on average and are being promised job and base protection, so the fight is really about future workers.
