American Airlines probably thought it had its staffing problem figured out when it sent out an internal memo requesting that paid employees sign up for additional unpaid shifts. Unfortunately for the airline, the memo leaked online and the response was not favorable.
On June 7, a Twitter user leaked the memo to the public. It encouraged American Airlines employees at the Dallas/Fort Worth International Airport to sign up for three six-hour shifts in addition to their full-time work schedule. The additional shifts would not come with extra payment on top of their normal wage.
