Recently one of my team leaders gave me two weeks notice. This is a nice set back for me and my company as he was the highest person in my company for team work and project management. To make things worth, this is the second time in two years that someone is this position decided to leave the company. Each one of them left for different reasons. This one said that he feels he reached a wall and can't improve himself with the tools around him so he wants to work for a bigger company with more challenges. I am wondering, lets just say that what he is saying is true about wanting to learn more somewhere else. What should be my turnover ratio in a team leader / project manager position? (he worked in this position for 1 year two month and the guy before worked for 1 year 5 month). I am aware that someone reading this post might think that there are more issues going on but let's just say that everything else is ok. Is it just a coincident that two people left in just over a year in the position? How can I keep this for happening again? Any advice?
