Earlier quoted context omitted.
The responsible action, is for the business to accept the overbooking as their fault, and arrange alternative traveling plans for their employees. Forcibly removing a customer due to overbooking should never happen, and a customer should be able to refuse. His actions while extreme to some, were reasonable IMHO.
On this note, can someone ELI5 overbooking? Why is it so hard for these companies to just not overbook? Genuinely asking.
I've never seen EasyJet or Ryanair overbook flights (and they operate at WAY higher load factors that legacy airlines - Ryanair is up to 97% load factor on average).
Edit: looks like Ryanair actually doesn't overbook. "Ryanair is the only airline in Europe that does not overbook its flights; therefore Ryanair has eliminated the possibility of passengers being denied boarding due to overbooking."
