Northern Gas and Power has been named the best company to work for in the UK in a new league table.
Tech companies Fourth and Equal Experts came second and third in the list respectively. Meanwhile, Facebook is the biggest company to make the top 20 list, rated 11th.
The Chartered Management Institute (CMI) and careers website Glassdoor analysed reviews of over 700,000 companies listed on Glassdoor's website. The result is the first ever Leadership and Culture at Work: the CMI/Glassdoor Top 20 Report, which focuses specifically on companies with the best workplace culture and leadership development, according to their employees.
Companies such as Northern Gas and Power were ranked highly due to their focus on management behaviour, and ensuring they develop, promote and boost the morale of their employees.
Patrick Woodman, Head of Research and Advocacy at CMI, said: "The companies featured in the Top 20 point towards a new way of defining management.
"Traditionally, getting on at work meant getting into management and climbing the ladder, but this hasn't always led to a perfect fit between people's skills and the demands of the role - especially when employers spend too little on training.
"Many of the best employers are now changing how they do things to make sure they put people with the right skills in the management roles that are critical to their company's success."
