A judge has ordered unions representing mechanics who work for American Airlines to fine workers whose actions result in flight delays. This order was issued to force mechanics to discontinue work slowdowns. The collective action that employees have been engaging in is part of an ongoing battle between the unions and the airline. Employees are upset about delayed contract discussions and have been protesting by engaging in slowdowns and using other tactics to disrupt airline operations.
