I HAVE heard of problems. Not problems I guess, just "issues" to be aware of. US companies are required to allow time off (i.e. dropped trips) for military duty - foreign companies are not. I don't work at Cathay, but have spoken with reservists who do - all of which work their military schedule around the airline schedule (ENTIRELY- i.e. no mil leave). I have been told though, that if a reservist's unit were activated, then said reservist would be put on leave without pay, rather than being fired.
I'm interested in Cathay, but am somewhat hesitant for this very reason.
