What is an alternative to job decriptions for a small business?

I have been researching job descriptions, the pro%26#039;s and cons, the hows and so on for our small business. The goals behind job descriptions are very good, however most managers and employees grumble and complain and drag their feet on them. Is there a better approach? One that managers and employees both, won%26#039;t groan so much at?|||Sometimes employees only do what is in their job description and nothing more a way of getting them to work on other tasks is to replace job descriptions with a more flexible type. You should assign each employee with a daily priority task these are completed by who they are assigned to first. and once they are completed they can check a list of work that needs to be completed. All employees can check the list pick a job and do it.
