One person complaining on Wired about "... says she ... had seen too many colleagues decline to speak up during internal meetings out of fear of retaliation for raising issues or proposing far-out ideas." that is evidence of at least one anecdotal individual personal issue. HOWEVER, the vote being "overwhelming" would seem to indicate they have a severe company culture problem not just one anecdotal issue, its not like she was the only one voting for the union LOL. I've worked at companies with and without unions and the ones that had a union, severely needed the union due to incredibly toxic workplace culture combined with a total lack of management accountability for their responsibility/behavior. Generally people won't bother keeping a union going unless they badly need it, given the enormous resources stacked up against them against forming and operating a union... It has to be a pretty awful workplace if forming a union against all that opposition is somehow still the better path... The quality of management has certainly not improved over generations or decades, so an era of declining union membership is probably not an indication of there being too many unions LOL.
