I'm non BM so please don't bite my head off if I'm wide of the mark.
It seems to me flight crew have at least some degree of responsibility for aircraft, crew, passengers, maintenance at out-stations, fueling, incidents etc, punctuality, standards and of course safety.
Some airlines then also want you to take some responsibility for their rostering! And more than half the posters here think its a good idea!! Maybe we should get invloved in payroll and other departments ( because getting paid suits us! ). Wise up people.
