How to stay loyal to the company? Part 1

Have you ever wondered how you can make an employee stay loyal to the company? There are always turnover of employees every year. I remembered when we were in Primary school, we were made to say the Singaproe pledge before our class starts and it goes like this:

We, the people of Singapore
Pledge ourselves as one united people,
Regardless of race, lanugage or religion,
To build a democratic society,
Based on justice and equality
So as to achieve happiness, prosperity and
progress for our nation.

So what if companies have their own pledge? I thought of many versions, and this is one of them:

We, the employee of XXXXX (Company's name)
Pledge ourselves to work hard for the company,
Regardless of normal shift, morning shift, afternoon shift or night shift,
To be punctual for work everyday,
Based on loyalty and MBO,
So as to achieve high revenue, high profit and low turnover in our company.
