Employees can now share their opinions about employers online. As a result, companies face new reputation risks that can affect their customers and shareholders.

For the third year, 24/7 Wall St. has identified the nation’s worst companies to work for. 24/7 Wall St. analyzed thousands of reviews from jobs and career website Glassdoor.com and selected the 11 companies with the lowest ratings.

Many of the companies on this list continue to be in the retail sector. As a result, complaints tended to focus on wages and hours worked. In many cases, these concerns focused on how difficult it can be for sales employees to meet targets that qualified them for commissions.

In other instances, employees complained more about how they thought a company was mishandling its customers. In the case of the Children’s Place, employees protested the pushy sales tactics. Jos. A. Bank employees wrote that the company’s changing product prices made it hard for them to make sales.

However, employees working in retail are not all unhappy. Scott Dobroski, associate director for corporate communication at Glassdoor.com, suggested that pay plays a big part. “We know that compensation is the number one factor job seekers consider when determining where to work.” Starbucks and Costco are examples of retail companies that offer benefits or pay above the industry average and that employees rate highly.

A significant share of employee grievances was directed at middle management. Workers at these companies were also highly likely to disapprove of their CEO. Chief executives at 10 of the 11 worst companies to work for received positive approval ratings from less than half of their employees. At six of these businesses, less than 30% of workers endorsed the CEO.

In the case of a number of these businesses, such as RadioShack and hhgregg, falling revenues, weak earnings and a sinking stock price may all contribute to lower employee morale and negative perceptions of executive performance.

However, negative employee opinions are not always a direct reflection of a company performance. Dillard’s has been a Wall Street darling. The company’s stock price has risen tenfold in the past five years.

To identify America’s worst companies to work for, 24/7 Wall St. independently examined employee reviews on Glassdoor.com. To be considered, companies had to have a minimum of 300 reviews. Of the more than 500 companies with more than 300 reviews, 24/7 Wall St. identified the 11 publicly traded companies that received the worst scores — 2.4 or lower. Employee totals are from each company’s latest 10-K filing.

These are America’s worst companies to work for.
