Proper communication is the hallmark to respect. Without it, nothing can be accomplished.
It is not uncommon across businesses that people that have a supervisor honestly believe they are smarter than their supervisor. Most of the time, some actually are. There are two different ways these situations play out, the first is that the supervisor realizes that the person under them is actually smarter than they are and relies on them to help them grow their own career for a period of time. The second is a bit uglier, they play nice, try to give them more stern direction on how they work and ultimately make an enemy incredibly quickly.
I have witnessed first hand new managers who have not even bothered to introduce themselves before giving an employee constructive criticism. Not a good way to start a relationship. It was akin to someone coming over to dinner and before even saying hi, taking a bite of food and saying something like
“this could use some more salt”
Everyone deserves respect in the workplace and for any and all new managers out there, you should have a very good 90 day plan in order and ready to present to your team so everyone is on the same page. Don’t disrespect your employees intelligence or inherent skills on day one without a thorough understanding of the business, something that can only be gleaned during the first 30 days.
