Having been in some kind of workplace for decades, I have learned that one needs to be excellent towards the people who works with one, to paraphrase Bill and Ted. Here are three:

The first one is well known, and here I am merely confirming that I have found it true experientially: If you are a boss, manager or owner, then if you value an employee, then you have to be proactive in making sure they are happy, productive, successful, feel safe and having a meaningful work life.  If you don’t you stand a good chance of losing that employee.

The second one is less well known: If you are employee and you appreciate your boss, then you have be proactive in making sure they are productive, successful and finding the workplace a good place for them.  A different version of this is well known to even (and maybe especially) cynics – make sure you keep your boss happy.  But this conventional wisdom is centered you.  If the boss is happy with you, then they will not fire you. And maybe arrange for higher pay and promotions for you.  But what I’m talking about is different. It applies to senior folks that you actually appreciate.  Help them so that they stay. 

And the last is one that people think least about: If you appreciate a peer, try to create conditions so that they stay and don’t leave or get forced out.  Because they are not in your chain of command, it is easy to think that there is little you can do or need to do.  The peer sinks or swims based on their competence.  But that’s not quite true.  You are part of their environment and you contribute towards making it a desirable one or a poisonous one.
