I assume thats based on the 900 flying hours & not total working hours (check-in to check-in). The cabin tech would also be getting shift allowance for working shift on top of the basic, so add's insult to injury for those poorly paid FSM's!!!!
Ok add 300 hours to the 900. Even working it on 1200 hours you would need to be licenced to earn more as a technician. And that includes shift pay. Whichever way you paint it the money is almost the same. You seem to know how much both Cabin Crew and Tech's earn and this is getting boring so get a calculator out and work it out for yourself.
I am not trying to make anyone feel guilty for wanting a
moderate pay increase. I am only pointing out that perhaps things are not quite as they initially appear. When you compare rates with other skilled staff they are reasonably similar.
