HOW CAN I INCREASE EFFICIENCY OF A BUSINESS OPERATIONS AND KEEP CURRENT EMPLOYEES HAPPY.

Respect your employees. Use their ideas in your business plan. Pay them top wages and provide superior benefits.

Since this is not my area of expertise, I searched Google under the key words "job satisfaction factors" to get these possible sources:

http://findarticles.com/p/articles/mi_m3495/is_8_50/ai_n14933129
http://en.wikipedia.org/wiki/Job_satisfaction
http://www.buzzle.com/editorials/6-23-2004-55791.asp
http://www.thefabricator.com/ShopManagement/ShopManagement_Article.cfm?ID=304

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps a little more. Thanks for asking.
