Hi,
First and foremost, a good human being can only become a Human Resource professional due to various reasons. A piece of paper or certificate does not determine the quality of an HR person. The most important points a HR professional should possess include patience, politeness, manners, being a good listener, able to handle all kinds of situations, and last but not least, a down-to-earth attitude. A layperson may not naturally have these qualities due to their day-to-day activities, pains, trials, and troubles, etc. Therefore, an HR professional should understand the agony, pain, desperation, or frustration of all human beings. I hope you will agree with me.
Cheers! Joe
