I've been down that road too and it wasn't
that bad. I actually disliked being IN a union more than I minded working WITH unions. The "16" good ones are still the same theoretical number of good ones union or not.
The good ones are usually good because they like money. OT = win for somebody on jackpot day when ya gotta have it NOW. FWIW I'm pretty sure the IH guys building cubs were represented (big strike in 80? 81?).
