From my recollection, step 1 to 13 is FO and Captain starts on step 14. So, most FOs see a good jump in pay when upgraded from say step 6 to 14 whereas the steps to 13 are for those who "wish to" remain in the RHS.
Skippers now go from step 14 to 35 which means after 15 years as a Captain you are not pay frozen anymore. There are now 5 more years of "financial enticements" to stop the experience leaving (which isn't happening as I met another 2 senior fellows leaving shortly) after notice expires.
Safe flying and enjoy that 8AED / HR pay raise.
