What ethical conflicts could airline pilots face if the industry moves to single-pilot flights?

A possible shift is in the works in the aviation industry. The Federal Aviation Administration and members of the U.S. Congress are investigating legislation to allow cargo pilots to operate single-pilot flights. Research is being conducted into what technologies would be necessary to enable single pilot planes. Airline pilots are pushing back. The International Brotherhood of Teamsters Airline Division says that single-pilot flights would be unsafe and would put valuable freight assets and the public at risk. Also, they would affect staffing levels at major logistics carriers, such as UPS and FedEx. If this idea takes off and is embraced by lawmakers and the public, the practice could make its way to passenger airlines as well. Even autonomous planes could be a possibility. However, industry safety groups say that members of the public are watching what happens with autonomous vehicles to determine whether such technology practicable.
