In a position like that you almost have to take a “durrr, I dunno!” attitude to everything, because if you try to talk to salaried people about what you need to do your job, you are looked at like a dog who just started reciting poetry.
Every now and then a salaried person will try to engage, take you seriously, but once it bounces up the chain of command that an hourly person is acting like they have something to contribute, it will be quietly shut down.
Seems like the business model requires hourly people stay out of the “brain space” entirely. Otherwise you’d have to pay them a living wage.
Really despicable way to treat people IMO. I don’t see why you wouldn’t want people to be proactive about solving problems.
The again, I’ve seen similar attitudes from engineering managers towards their direct reports.
