Every contract negotiation since BK (when ALPA negotiated PS as part of huge wage reductions) there has been attempts by the company to "monetize" PS calculations, ie reduce them for a notional few % more in rates. The first contract post BK they were successful (would love to know what PS would be had the original calculations been preserved) and luckily in contract 2016 ver 1 (which was not passed by membership) wouldve again reduced the PS calculation to match what mgmt had already reduced the non cons to. When we rejected that change in contract 2nd round, then mgmt quickly raised the non cons back up to what the PWA had preserved. Only the latest contract negotiation did not include a proposal to reduce PS for more % on rates.
