Just to clarify, "less training" in this discussion means less full initial training for aircraft changes. The topic is potentially allowing longer freezes and/or pay banding to de-incentivise people voluntarily choosing to change planes chasing small raises. That would reduce required manning if successful though, so some have suggested increasing vacation or something else in proportion to make it staffing neutral.

No one is suggesting reducing the time or quality of the actual initial or currency training in exchange for something else.
