Cubist Pharmaceuticals, Inc. (NASDAQ:CBST) today announced that it has been named one of the Top Places to Work in Massachusetts in an annual employee-based survey from The Boston Globe. This marks the sixth consecutive year that Cubist has been named to the list, every year since the survey began in 2008.

"Being recognized as one of the Top Places to Work for six years in a row is a source of great pride for me personally and a reflection of the incredible people that make up our organization and the passion they bring to our mission," said Cubist CEO Michael Bonney. "I'm pleased that we have continued to enhance our strong culture while experiencing tremendous growth this year as we build our international business and expand our pipeline."

The Boston Globe Top Places to Work 2013 magazine was published in The Boston Sunday Globe on November 17. In addition, this issue will be featured on BostonGlobe.com and Boston.com. The rankings were organized into four categories: Largest, Large, Medium, and Small companies. Cubist was ranked 25th in the Large employer category. Rankings were based on composite scores calculated purely on the basis of employee responses.

The Boston Globe's 2013 Top Places to Work survey, conducted by employee survey firm WorkplaceDynamics, measured more than 76,000 individuals' responses to statements regarding six key factors related to employee happiness, including company direction, execution, employee connection, work load and responsibility, management, and pay and benefits. Least important were pay, benefits and work-life balance, with survey subjects placing much higher importance on employee appreciation, confidence and feeling that their work is meaningful. WorkplaceDynamics also found that of all the cities surveyed, employees in Boston were most enthusiastic about their companies, making Boston the top of the Top Places to Work.
