Yes, they mean the people, I'm aware of that. I find it's helpful to remind people that "the company" is just people, because some here seem to have this obsessive view that because "Apple did it", it must be the correct thing to do.
And not every decision is going to be correct or what's best for the company.
Managers are not infallible. You do know this, right?
No, it's their boss who decides what is or isn't allowed. Just because a manager decides something does not mean that it is what's best for the company.
Management completely mess things up because they thought it was best and leaving the people who do the actual work to clean up the mess is a ridiculously common occurrence.
Management staff included.
I don't know what world some of you work in, but some of us (even when not owning our own companies) have worked for managers that value the input of their staff. Sure, if you ask for a million dollars a year to mop up sick at a kindergarten you're not likely to get it, but if you provide actionable feedback that can improve employee conditions without having an overall negative impact on the company, good managers will be all ears.
Have you never heard the phrase "happy workers are good workers"?
