On Glassdoor, current and former employees of companies worldwide can share both quantitative and qualitative data about their workplace experience in a survey designed to capture a genuine and authentic inside look at what it’s like to work at particular jobs and companies. The survey asks employees to rate their satisfaction with the company overall, and key workplace factors like career opportunities, compensation, benefits, work/life balance, senior management, as well as culture and values. In addition, employees are asked to describe the best reasons to work at their companies as well as any downsides.
The Best Places to Work are determined using company reviews shared by UK-based employees between November 3, 2014 and November 1, 2015. To be considered for the UK list, a company must have at least 25 Glassdoor-approved company reviews from current and former employees during the window of eligibility. The final list is compiled based on Glassdoor’s proprietary algorithm, and takes into account quantity, quality and consistency of reviews.
