Generally you will find that if a company has good, solid management practices, they often also have family friendly practices and policies. Good managment practices often create an environment where people want to work.
One of the most well recognized lists of good companies to work for is the Fortune 100 Best Companies to Wor For. Companies are rated on a variety of aspects including benefits offered, turnover rates, job growth and number of women. Fortune has recently relaeased their 2008 list.
While one of these 100 companies may not be near you, you can first learn more about good management practices by learning about the types of benefits and policies that these companies provide for their employees. Further, many local organizations create lists similar to Fortune's which recognize good management practices at companies near you. For example, I am in Northeast Ohio and a local organization here sponsors the Northcoast 99 which showcases the top 99 local employers.
