From the time of POS18 being introduced to COVID hitting the major career carries were all recruiting. If you had the required experience you would get an interview. I assisted several CX POS18 pilots with their applications and am please to report that these guys left CX and now work for good companies. Companies where they have taken concessions during COVID but will return to their previous conditions once the industry recovers.
Once populations are vaccinated travel will return and good jobs with good companies will again be available to those with the required experience, so POS18 is OK for a 300 hour 172 pilot wanting some jet time. Not much use for anything else.
At the moment there are stuff all jobs out there, so hanging onto any job, even if it meant taking POS18 was the only logical option (something the company knew and exploited). I'm too old to join another company at the bottom, so I'm hanging in there and waiting for contract commands to return.
