Lately, I heard of many friends leaving their organisations. I learnt one lesson from it. Leaving may not be due to unhappiness or conflict. It can also mean one have stayed too long to see much and the job became a mundane thing to do.
Nothing much to learn…. next best thing is to leave, take on another job and continue developing. This is how a person has personal growth and development.
A good leader do not stop good staff from leaving, instead wish them the best to encourage them to grow.
