It’s worth noting that in government at least, traditionally union shops, there are occasionally white collar unions. Sort of.
I work for a large multi-county municipal water utility and we confusingly and chaotically have no less that four locals in three unions. The only people exempt are upper management and a tiny handful of confidential employees.
The big union is, unsurprisingly, AFSCME, with two locals:
1.) A “white collar local” that covers the engineers, computer programmers/IT, lab technicians/biologists, watershed ranger-naturalists, surveyors, hydrologists, secretarial pool/administrative staff, etc.
2.) A “blue collar local” that covers watewater/reclamation plant operators, mechanics, electricians, instrument techs, heavy equipment operators, truck drivers, meter readers, janitors, etc.
Then there are the 35-odd water plant operators, who decertified from the “blue collar” local above during a strike in the 1980’s, then recertified with a different union a decade+ later due to perceived vulnerability and management abuse. They are by state law legally barred from striking.
Then, quite bizarrely, there is the youngest local that formed less than ten years ago, covering a substantial ( but not all, it was initially opt-in ) portion of lower and middle management. Quite the contradiction, eh? It gives you an idea of management relations at my job. Dysfunctional? Oh my, yes.
At any rate it is interesting to note that in this most recent contract dispute ( recently settled ) it was the “white collar local” that was by far the most militant - they voted strike authorization to their negotiating team almost immediately. They argued the loudest, organized the most demonstartions, used the strongest anti-management rhetoric and did indeed threaten and were planning a walk-out until upper management caved ( well, compromised ).
The “blue collar local”, by contrast, traditionally much more militant, were rather less so this time. Something I attribute to the immense seniority of much of the skilled trades folk in particular. Mostly in their 40’s - 60’s and nearing retirement, they were a bit more complacent and comfortable than in days past.
All of which is to say that at MY job, yes, from my standpoint the “white collar union” is attractive, simply due to pre-existing tensions and the history surrounding the place. For all of its ( many, MANY ) flaws it forms an important protective/collective bargaining function. A worker-friendly Silicon Valley firm, this is not.
