If you impress the bosses, the most you can get is a higher increment and maybe a faster promotion but your worth will only be seen in that company,those who works hard all the time and have a good attitude in taking new challenges would have gained the experiences and will be more valuable as his/her time in the industry increase. Other companies will value him more and will pay a good ransom to poach him away. You cannot cheat your way thorugh the industry. Other people or other companies will know your experience levels.
