How do you judge the quality of a workplace? Ask the experts: The employees. For the 13th year, employee survey firm Energage has partnered with The Denver Post to determine the best places to work in Colorado. It’s not a popularity contest, and not everyone gets a blue ribbon. A select few are honored based on a scientific survey process. Bob Helbig Energage administers an employee survey that covers 24 factors and takes just a few minutes to complete.
