A workers union would never allow this. For example the ALPA in the United States where I live has strict rules about when the cockpit voice recorder can even be accessed and by whom. Even after an accident it’s virtually never released - only the radio traffic.
Amazon has used layers of 'delivery contractors' who 'employ' the delivery drivers to bust any unionizing. Recently it was ruled that Amazon is a co-employer so they won't be able to continue that tactic going forward. Amazon is a horrible company.
