1. Books-A-Million -Books-A-Million Inc. (NASDAQ: BAMM) employed roughly 5,400 workers at more than 250 U.S. stores as of the beginning of this year, most of which were part-time. Like many retailers with unhappy employees, Books-A-Million institutes commission-based pay structures. Perhaps as a result, high stress and low pay were common complaints on Glassdoor.com. One employee wrote, “to[o] much stress for the pay, very low pay, low chance of promotion, hours are based on magazine and discount card sales. Even if you’re normally good, if you have a bad week you get cut.”

Just 14% of employees said they would recommend this company to a friend. Books-A-Million’s culture and value were rated just 1.8, the lowest among companies reviewed. CEO Terry Finley is also not popular, with just 22% thinking he is doing a good job. Over the past several years, the company has struggled to keep up with other large retail and online book sellers like Barnes & Noble and Amazon.com.
