When it comes to happy employees, grocery chain Wegmans tops the list.

The grocer was this year’s top retailer on Fortune’s100 Best Companies to Work For” annual list. Hilton took the top spot, but here RIS breaks out the best retailers to make the grade.

Fortune partnered on the list with analytics firm Great Place to Work, which determined the list by conducting America’s largest ongoing annual workforce study, representing more than 4.3 million employees this year alone.

Employees responded to over 60 survey questions. Eighty-five percent of the evaluation is based on what employees report about their experiences of trust and reaching their full human potential as part of their organization, no matter who they are or what they do. Great Place to Work analyzes these experiences relative to each organization’s size, workforce make up, and what’s typical in their industry and region. The remaining pieces considered include an assessment of all employees’ daily experiences of the company’s values, people’s ability to contribute new ideas, and the effectiveness of their leaders, to ensure they’re consistently experienced.

To be considered, companies submit an application documenting over 200 datapoints describing their HR programs and practices and need to employ at least 1,000 US employees. Great Place to Work then conducts an anonymous survey of each company’s workforce. To ensure surveys truly represent all employees, Great Place to Work requires enough people in each organization to respond that results are accurate to a 95% confidence level and 5% margin of error or better. One part of the total score is based on evaluation of company programs and policies, while three parts come from an analysis of employees’ survey data.

From company perks to opportunities for innovation, here are the five best retail companies to work for.
