More than 68,000 Houston-area employees evaluated their employers for this year's Top Workplaces section - rating their companies in such areas as opportunities for advancement, the value of their pay and benefits, and their bosses' communication and management skills.
Pennsylvania-based research firm WorkplaceDynamics invited 1,391 local companies to participate and surveyed 285 of them, then tallied the results to determine winners. Anyone, such as an employee or a customer, could nominate a workplace for consideration.
The Houston Chronicle is one of 38 newspapers for which WorkplaceDynamics compiles workplace rankings. The company surveyed 1.2 million employees at 5,626 companies to generate the top workplace lists.
The local winners will be considered for a national ranking in January.
The local list, which made its debut in 2010 with 100 companies, was expanded to 150 companies in 2012.
In total, 28 employers have earned spots on the list all four years. This year, 51 companies are new to the list.
The local survey participants employ 140,028 people in the area; 114,071 of the employees received surveys, and 68,446 responded.
The organizations on the list included public and private entities and nonprofit groups.
WorkplaceDynamics reached out to companies with at least 50 employees.
Included in the Houston Top Workplaces rankings:
1 Top 35 Large (out of 47 participants with 500 or more employees in the region)
1 Top 45 Midsize (out of 98 participants with 150-499 employees in the region)
1 Top 70 Small (out of 140 participants with 149 or fewer employees in the region)
Notes about the survey
WorkplaceDynamics required a response rate of at least 35 percent for employers based in the Houston area.
For employers with 85 or fewer employees, at least 30 responders were required. For larger employers, surveys could be sent to employees in a random sample. For employers with 2,500 or fewer employees, surveys were sent to at least 500 employees. For employers with more than 2,500 but fewer than 5,000 employees, surveys were sent to at least 20 percent. For employers with 5,000 or more, at least 1,000 surveys were sent.
Employers are ranked by size bands because smaller employers tend to score higher than midsize employers, which in turn tend to score higher than large employers.
