Recent research by Investopedia revealed 9 companies out of Fortune's "100 Best Companies to Work For" that have never had layoffs. They include: Nugget Market, Devon Energy, Aflac, Quick Trip, The Container Stores, NuStar Energy, Stew Leonard's, Scottrade, and Publix Supermarkets.

If you would like to create a company that also doesn't have layoffs, here are some common themes from the above examples:

- Cross-train employees so that they can fill various roles.

- Keep branches relatively close together, so that employees can easily move from one branch to another.

- When employees leave, don't replace them automatically, especially during slow times.

- Grow conservatively. That way, you don't create an internal "bubble" that can't handle short-term downswings.

- Create flexible positions via telecommuting and flex schedules.

- Stay private and closely held, so that you don't have to pay out dividends to shareholders.

- Pay annual one-time bonuses instead of giving large raises, so that you don't force seasoned employees to become "over-priced" with high salaries. Also, you can cut bonuses instead of employees when times get tough.

- Make a commitment in your culture to avoid layoffs at almost all costs.

- Avoid excessive debt.

The companies that have followed the above strategies also offer great benefits and training. As a result, top talent comes to them. These companies show that even in tough times you can do well by taking care of your people.
