Unions do NOT allow for recognition/award to the best . . . all are supposed to be treated equally within seniority. This sucks big ones!
When I first went to work for the PD as a Reserve PO, working my first shift I was told "it all counts for 20" (meaning don't look for trouble, make arrests, etc. as everyone gets a pension after 20 years no matter what you do/don't do). Totally foreign to me, as I've worked in industry all my life where tenure and seniority were never part of the picture.
My Wife was a teacher (2 states, 2 school systems) for 6 years, serving as a "traveling" speech therapist before heading into industry. Somehow I was almost roped into awarding a retiring teacher her plaque by the union (don't ask!), as nobody wanted to do it . . . she was a known alcoholic and they were happy to see her go.
At DEC our group had 2 alcoholic secretaries and we really couldn't do anything about them either . . . both went to detox to avoid HR actions against them, eventually one of them cleaned up her act. This was non-union.
I'd love to see teachers rewarded (salary increases) based on performance, but I never see it happening in the US.
