Recognize the actions you want repeated

I always find is funny when a manager complains about a team member not doing the right thing. My first question is did you train him and do you recognize the right actions when they happen. And what I mostly see is leaders that expect employees to know everything they already know and don't have any recognition programs in place to coach the proper actions. It's not heard to put something in place to drive the correct results. It's just many don't see that as a leaders job.

If your not correcting bad behaviors then your just plain coaching them.

A learning culture is a must

This week we focus on train always. Create a learning environment that develops people through education.
Invest in your people and reap the rewards. Roll playing is a great tool for training. Always look at what you can do to develop your team. Webinars and peer groups are great resources

Also look at starting a mentorship program to pass along the knowledge of the veterans you have. Work on these and reach out for help if you need it.
