> feel safe to share what they think.

This will never be the case. Never. Engineers can sometimes be slightly more open in technical arguments... senior engineers to much lesser extent - seniors learned that sharing what everyone truly thinks is prohibitively expensive to their career, no matter how much amazing boss you think you are.

Anything more than technical stuff, especially management style -- forget it. No one will share what they think, unless the situation is beyond repair, and at this point junior engineers will rather share to the skip level manager or HR (futile, thus junior engineers), and seniors will just a) check out or b) leave.

Cute.
