To say that they can freely express themselves...no. We're pretty regulated in that fashion. There are policies that are supposed to ensure that career managers and leadership have open door policies so they can have these kinds of discussions at the lowest level, but that's entirely subject to the personalities who are in those leadership positions, because, unfortunately, not every person who gets into a leadership position is fit to be a leader. That's just the reality of it.
There's also the grievance system within the military that can be utilized, but there are also a lot of trust issues that the military community has about the grievance system. A lot of allegations of those same poor leaders, who will take a grievance, throw it in the garbage, rip it up or use it to smear someone's campaign.
While those mechanisms exist, there's not a whole lot of trust in them.
