Training adds to a person's toolbox. But it does enhance and it can be very effective as a recognition reward. I like to use the analogy of a red wagon. A new supervisor without much experience behind them has a pretty light wagon. But by the time a supervisor is 40, that wagon is filled with experiences, tools and ideas.
Training helps to fill the wagon.
They look for HR departments to be customer-service oriented and to be responsive to questions and concerns. My job is to support the employees here. Having the ability to forecast change and deal with it. Also being genuine and keeping in mind the human element because otherwise you're going to have trouble adjusting to change. Also displaying to employees the significance of learning and growing.
