please explain me an easy way to make me understand and please write down one easy example regarding this sentence. " When employees volunteer, they feel in charge of what they are doing. They will have the opportunity to organize what to do, when to do it, and where to do it. All these gives them some sense of empowerment because their managers are not controlling them. Empowering employees boosts their morale and increases employee retention. Increasing employee retention helps retain useful and productive talents within the company. Eventually, all these will transform into higher returns for the company (TD Bank)."
