if there is anything i believe in is the word of God: Have you seen a man diligent in his work he shall stand before kings and not mean men. However having worked for a company for three years+ God has been so good to me i must acknowledge GOD for that even though i still ask him(GOD) for promotion.

I have been diligent in my job. ranging from Punctuality, detailed reporting, Training of new staff among others as it relates to job function. But it seems nothing is been felt be my direct superiors and perhaps higher superiors "so to speak". Since diligent in work make one stand before kings why am not yet recognized regardless of the fact that my ideas i have propounded to my direct superiors has driven high sales and my past inputs has also made a considerable impact. why am i yet to stand before kings?

Great question.

I will try as much as possible to be honest in my own opinion.
Remember every thing worketh for good. Diligence thus brings promotion most times but it can be delayed due to human factors. One of those factors happen to be when you have a manager you are reporting to and the manager also reports to higher authority. Some managers are always after their own upliftment and not that of their subordinates. Whatever good you do or extra effort you put in to accomplish some certain tasks is not heard at the top level. But my candid opinion: don't stop being diligent because one day someone within the company will notice and stand for you even when your direct manager cant.
Diligence pays.

Diligence pays. know your organisation, you fellow employees. In a typical Nigerian Organisation, eye service brings promotion before diligence! If you are not been rewarded as envisaged, I all advice a change.
