As a general thought re: the direction of our union and our wages/bennies and rights/protections, to sit back and count our blessings is company-thinking.
This is especially the case in a RTW era when unions -- not just the Teamsters -- are by and large quietly fading away, authorizing (hell, even proposing!) concessions, and hamstrung by generations of red-tape intended to divest labor of the power to fight back ...
I have my doubts that the rank and file is capable of self-directed militancy, which is always a gamble ... but it's pretty clear that, historically, rank and file activity is the source of all gains us peasants have ever won, not benevolent 'leadership' ... And I'd rate it a sure bet that if the members don't insist on reversing the tide, then we should expect further concessions.
Final musing. At docks I've already delivered several over-70s on skids out of package cars (I know this has been discussed in other threads.) When receiving helps me unload the bastards by hand, they nearly always shake their heads. I've told them we enjoy the right to call for help. No one's impressed. It's an embarrassment, and not less of an embarrassment because it's been that way for 25 years.
