It’s not a partnership, you’re their manager, you have more power by definition. It’s risky to offer any criticism to a manager. Does your team know that doing so is a safe action, regardless of what they say? (And is it true?) Do you request anonymous feedback? What is the upside for them if they offered critical suggestions? If they say you’re not doing something well that you think you do, how do they know it won’t cause them problems down the road? Will you be defensive or open to hearing it if they say something you disagree with? IMO this can be risky for you too, because you may have a wider point of view on things, which could cause you to have to disregard some points of criticism, which could in turn make it look like you’re not respecting your team’s opinion. I know from experience both as a leaf node in the company and as a manager, that sometimes people being managed can get the wrong idea about how things are going down and start to believe that they see obvious/easy solutions, while the manager’s point of view is broader and problems are not so easily fixed.
