We have a saying in work about one of our managers,
'Quick to criticise, petulant to praise.'
And that can be said for the majority of this nation.
When something goes wrong, or someone is slow to react or we 'think' we have been unjustly treated we come down like a ton of bricks. Yet when someone performs an unselfish act we dismiss it as 'part of their job.'
I recently encountered problems booking in to a hotel whilst working away from home. The receptionists could not do enough to try to sort out a problem that was caused by the company I work for. They went out of their way to ensure I was booked in correctly, even offering to take a chance that by letting me into the room my company would eventually sort things out.
I refused to go to the room for fear of them getting into trouble, even though one was a manageress. When they did sort it out I promptly went to my room and wrote to their HQ saying what a fantastic team they were and they should be recognised for the effort they put into ensuring customer satisfaction. The following week I was pleased to hear they had been applauded by their bosses and given certificates and shopping vouchers for their professionalism. I in turn have made 5 very good friends for my small consideration.
So instead of moaning and complaining when something doesn't quite go according to plan try praising when something does.
You make enemies by being critical. You make friends by being friendly.
