Not sure that failing to meet requirements for the AOC in the first instance (what I understand from several sources in TL) falls under the banner of "challinging pathetic work practices"? How long has that shiny new beast been sitting on the tarmac waiting to earn money for the company?
I can also say that I know many FAs who would gladly argue that 1 to 50 is a tall order (depending on the sector). Regardless of how much time they have to get the service done, trying to commence an evac through two (or more) exits while the flight crew get the aircraft shut down is enough of a challenge for two FAs, let alone one.
FAs get precious little respect and pay in this business (particularly in regionals where they only have one or two to get the job done). I don't think they need people telling them they should be working harder and with more responsibility.
