FO roster is busy. If you are an RQ, then it is horrifically busy and not great for your personal life at all. Too many of your 'days off, free from duty' are rostered to occur away from home base in places like San Francisco or London - not with your wife/husband and/or children. Rosters are pretty much done at maximum legal limits these days and will probably be that way for a few years. Quite fatiguing.
When it all becomes too much after dealing with years of draconian COVID rules, no control over your life or your roster and work begins to affect your ability to spend quality time with family then you need to take compassionate or stress leave. Requests for leave are almost universally denied unless you get a medical certification.
Although medically approved stress leave will give you that much needed time at home to help care for your child with leukaemia, the downside of taking time off in this company is that the pilot managers will then call you into the office and punish you under the guise that you lack the 'strength & resilience' to be a captain and that your promotion has been delayed.
Cathay really has become an Orwellian dystopia off the back of COVID. Fantastic for management - not so great for employees.
