Now is a great time for workers looking for a job. According to the latest jobs report from the Bureau of Labor Statistics, the American economy added 250,000 jobs in October, and unemployment remained at just 3.7 percent, the lowest since 1969.

This tight labor market means that companies must compete to attract and retain talent. Each year, job search and salary comparison site Glassdoor determines the companies that are the Best Places to Work. Glassdoor analyzed company reviews across eight variables: overall company rating, career opportunities, compensation and benefits, culture and values, senior management, work-life balance, likelihood of respondents to recommend the organization to a friend and six month business outlook.
