Some people will complain, no matter what you do.
It’s easy to tell the difference between someone who complains constructively to help you, and someone who complains to drag you down. The constructive ones tell you what they like about the situation and offer a suggestion or two, in addition to their complaints.
Destructive complainers just complain. No compliments, no suggestions, just bitching and whining.
The question is, how far should you go to appease the complainers?
You could tell them to stick it where the sun don’t shine, and stand firm. They would probably complain more even if you made accommodations, right?
You could bend over backwards, explain your decisions, cater to their complaints and change course to make them happy. But will they still complain after that?
You could ignore them, hoping they’ll get the point. Some will go away (they’re always busy looking for other people to complain to), but some will come back and expect a response from you.
Either way, some people will complain no matter what you do. If you try too hard to appease them, you’ve let them win by dragging you down or changing your decisions.
Ask yourself this next time you hear a complaint: how much of it is really about you, and how much of it is really about the complainer himself?
And next time you hear yourself complaining, think about your intentions.
