Those both sound like situations where the majority has chosen something. Bias towards "yes" sure, but people also have a pretty strong bias towards NO CHANGE - unless things are bad.
I believe the general dislike of secret ballots among pro-union people has to do with the voting process being controlled by the companies. The accusation being that when the company controls the process, they are interfering in the result. Given the choice between coworker interference or employer interference... I'll pick coworker any day, they've got a lot less on me than my employer. If the vote could be truly independent and secret, sure... but burden of proof is high
