Staff contribute so much to a company and I strongly feel that they should be rewarded in many ways and a company should appreciate their work as they play a major role n making a company successful. Sometimes it does not feel that way in some companies and as a result there are many turnovers. Losing a staff is a sad thing especially if his/her contribution matters so much in terms of financial growth.
So I feel that motivation and keeping staff happy is a big challenge to a company.
The ways a company can motivate their staff would be:
1) Pay increment
4) Special incentives
5) Year end travel to overseas country
These are my opinion on how to motivate staff and keep them from leaving.
