True, its good to praise your worker, but it should be for the right reasons and at the right time. They should also be aware of the reasons you praised them. Then again over praising is bad so we should be careful not to over praise our workersAs for me I think the mistakes in praising employees is that when you over praising employees and make them doing something else to the extend they look at it that you won't do anything and doesn't take there work serious but I see no reason why they can't praise an employees because it's right and good praising employees for good work they doing or done
