Large employers
The Globe invited 1,076 employers to participate in its fourth annual Top Places to Work. Of those, 237 organizations went all the way through the process, allowing us to conduct a confidential survey of their workers. Research partner WorkplaceDynamics of Exton, Pa., specialists in employee engagement and retention, contacted more than 121,000 employees at those companies and received completed surveys from 73,813 individuals. Each was asked to grade their organization's performance according to 24 statements, ranging from "New ideas are encouraged at this company" to "It's easy to tell my boss the truth."
