I think Panama has been fair, based on past EK management decisions. They tried and succeeded in having a ridiculously short layover after an ultra-long flight. The only thing that changed that was consistent ASR's. They are still persisting in having pilots 'attempt' rest in unsuitable business class seats during a long flight. They place CRC's in the aft of aircraft, with the resultant concerns for flight safety and rest.
EK management will not do anything to track radiation levels for pilots, other than a 'perceived' tracking of such. I have no doubt whatsoever that the statistics or data will be massaged to suit the economic needs of the company.
These clowns don't give a rats ass about our health. The only recourse we have is to file ASR's.
