“punish in private, praise in public”.- Definitley a good place to start.

I have had a few good and bad leaders in CRM.  An overconfident or arrogant leader is never good, especially if they are just trying to compensate for not really knowing what they are doing ( ex. how to navigate terrain or deliniate a site).  Neither is someone with no confidence that makes it obvious and is constantly leaning on their crew to make decisions or wembling over them and slowing down the work when most crews are capable of working without a babysitter or having to babysit their boss.

If someone is new or unsure about what to do, a good leader won't belittle them for not knowing because we all know the CRM environment is way different than anything they teach you in school.  Newbies are usually curious and ask a ton of questions, this show that they are engaged and interested in doing a good job, not stupid.   Good leaders are prepared for this with a concise example of how things are to be done and when asks would explain it as how they or their company would like it done.

They also don't degrade crew members for just having a Bachelor's, I didn't to school for that long to have a superior disrespect the education that they also require me to have (like just calling someone a tech).  

A good leader will have high expectations, will recognize and reward them for being met, but will be understanding if the goals cannot always be accomplished.  

Good leaders will ask for input from their crew (even if they don't need it) to show respect and then delegate to responsible crew members and pair them with those that may need some guidance.

Bad leaders get upset when someone asks why we are doing something as if their authority or judgement is being questioned when they should simply explain themself because people are usually just looking for clarification. It is better to keep everyone well informed (without barking) so this does become an issue.

I could go on but I will let others throw in some thoughts.

Excellant comment, Diginit!  I couldn't agree more.  A few, simple, leadership skills could go a long way to making the crew happier and to making them function better as a team.  The moral of the crew stems from the top and it's usually the people at the top that need training too.

Thanks for the comments!
