You the boss!

While I have not professionally held the title of a manager, supervisor or as I call it "a boss" as a subordinate I have observed the do's and don'ts to managing others through being managed.  On top of being intelligent, ethical and being good at what you do I believe the next ten things wouldn't hurt to be good at being "a boss".

1 - Open Communication
You have to have an open line of communication in all aspects so that there is no guessing in the work relationship.  That goes from communicating performance to letting your employees know you aren't coming to work or are leaving early.  Today, my boss left the office early, leaving our team confused at where she was, if she was coming back and if and how we could reach her if an emergency occurred.  Literally, no one in my department knew where our boss went. 
2 - Empowerment
If you don't motivate your employees and instill confidence in them to do a great job, 9 out of 10 times your employees won't produce their best work.
3 - Transparency
While managers can't always tell their employees everything, like future plans not yet approved, the fact that an executive is retiring, etc.  However, if that is the nature of your job, as a boss, let your employees know that you will be as open and honest with them as their job allows.  Honest enough to share what you can, and honest enough to say when you can't.  When the economy was down back in 2008 my boss let me know early on, that there will not be any bonuses for me or anyone in the company and she was right.  It sucked, but she was honest.
4 - Approachable
Some bosses think that being a boss means to be mean, unapproachable and to have your employees intimidated by you.  This will cause resentment and actions driven by fear.  They will hate you and talk about you behind your back.  This one goes with number one, there will be no communication if you are unapproachable to begin with. 
5 - Engaged/Presence
If you don't care, they won't care.  Bosses who are detached or disengaged when it comes to the department they are managing run the risk of losing the focus of their employees.  A previous boss of mine seemed not to care if and when she came to work, when deadlines were approaching and if I was even doing my job.  At first I thought she just really trusted me, I mean I am a stellar employee, but then I began to notice that she was just not that into the job.  Maybe this was temporary, maybe she was going through something, whatever the case it led me to become resentful and overworked.  So, make sure as a manager, you stay tuned.
6 - Supportive
Employees need cheerleaders at work.  Support on projects, support during conflict and support in the growth of their career.
7 - Respectful
Disrespect does not yield positive results.  Again, this will get your employees talking about you behind your back.
8 - Secure/Confident
If a manager is not secure in their abilities they tend to hoard work and not work towards developing their employees to be successful.  Most times employees don't want to stay in their same position forever, they want to grow.  If the manager thinks that their subordinate will outshine them or pass them up in some way, they will be hesitant in providing opportunity.  If you feel like that, than you as a manager should take up a course to better your skill set instead of holding someone back.
9 - Lead by example
Do as I say, not as do, works best coming from a parent or guardian.  Coming from "a boss" ummm, not so much.  This will cause confusion and in my opinion lead to unethical behavior.  You mean to tell me that if you are a boss you act one way and if you aren't you act another - not good.  The reality is EVERYONE has a boss unless you own your business, so you will eventually have to answer to someone.  How about you just do the right thing and use your best judgement when in doubt and showcase good professional behavior to your employees.
10 - Human
You did not start your job as "a boss".  We all have to start somewhere, learn something and make a mistake along the way.  We are all human and that includes our bosses!
