For the past three years, the Star Tribune and the Pennsylvania research firm WorkplaceDynamics have set out to identify Minnesota's Top Workplaces. We have consistently found that good employers share similar traits that workers consider important, among them:

• Feeling "genuinely appreciated."

• Believing that the organization is "going in the right direction."

• Having "confidence in the leader of the organization."

Some familiar names have ranked among the top large-company workplaces in both 2011 and 2012, including gas-and-groceries chain Kwik Trip, realty company Keller Williams and Bremer Bank. Other top ranked employers last year included the Minnesota Twins, Graco Corp. and Cargill Inc. (See last year's report at startribune.com/topworkplaces.)

The Star Tribune is once again working with WorkplaceDynamics to produce the Top Workplaces publication for 2013, and it's time to get started on our 2013 survey.

If you know of a company, nonprofit or government agency with 50 or more employees that deserves to be considered for this year's Top Workplaces ranking, go to startribune.com/nominate. You can also call 612-605-3306.

We encourage individuals, employers or employees to nominate their companies and tell us what makes them great places to work. Employees at participating companies will be surveyed between January and April by WorkplaceDynamics, our survey partner that also conducts surveys in more than 30 major metro markets.

The nominations must be submitted by Feb. 22. In June, results will be published online at StarTribune.com and in a special print section. Thanks in advance for your help.
