How could motivation help to improve the productivity of the organization and obtained its objectives?

It takes more than just motivation to improve productivity. It takes seeing employees as human beings first, employees second. Trust from the employer and one deceitful act will cost the employer plenty in the end. My husband and I run a crew of over 30 men and that's how we work it. There is the odd one that will take advantage on a given situation, but on the whole it works very well. With those that take advantage they are hauled into my husband's office and given ultimatums .... consider yourself lucky, do your job or you're out the door. Kindness and sternness go well hand in hand. To motivate people you basically have to give them a goal and at the end of that goal there has always got to be a reward. This world is all about money and not much else so bonus' are well accepted or extra time off for a job well done. Many companies today don't really seem to care and will not treat their employees well. It's actually a very unintelligent way to run a business be it a small or large organization. If you don't treat the people working for you fairly then you lose productivity, loyalty and may lose some good people to other companies.
