The list is determined by a survey sent to both the employers and employees from hundreds of companies in the state.

Sheetz is among the list of 100 Best Places to Work in Pennsylvania. The alphabetical list was revealed this week by Team Pennsylvania Foundation and the Pennsylvania Department of Community and Economic Development (DCED.

Sheetz was listed in the large employer category.

Team PA is the lead sponsor of the survey and, along with DCED and the Central Penn Business Journal, a founding partner of the program, which pays tribute to top companies around the commonwealth. The numeric list of winners will be announced at a celebration dinner on Thursday, Dec. 3 at the Lancaster County Convention Center in downtown Lancaster, Pa.

“Team Pennsylvania Foundation is honored to support a program that celebrates our two most valuable resources – a quality workforce and world-class businesses,” said Ryan Unger, acting president and CEO, Team PA.

The 2015 Best Places to Work list represents companies with over 22,900 employees throughout Pennsylvania.

The Best Places to Work in PA Program is generally made up of two groups of companies: 50 small/medium-sized (25-249 employees) and 50 large-sized companies (250 employees or more). Through the research process, a survey is sent to both the employers and employees from hundreds of companies from across the commonwealth.

However, this year, more medium-sized companies scored higher marks than large-sized companies, so the list is made up of 74 small/medium-sized firms and 26 from the large category.

Winning companies achieve the highest combined scores in a twofold evaluation: review of a company’s workplace policies, practices, philosophies, systems and demographics (25%); and results of an employee survey to measure the employee experience (75%).

Using a formula similar to Fortune’s “100 Best Companies to Work for in America,” the Best Companies Group surveys and scores the workplace practices survey along with the employee survey and each Best Places to Work candidate is given an overall score.
