The telecommunications industry is a huge employer. Its reach spans every technology-related business sector and it remains at the heart of the entertainment world, as well. Prospective employees face a dizzying array of companies from which to choose. Many factors go into picking the right job, but it’s worth taking a close look at the CEO. It may seem that Chief Executives operate up in an ivory tower, but their influence reaches much farther than you’d think. They are the captain of the ship, and the impact of their strategy, decisions, and even personality can often be felt right down to the smallest everyday details.

We’ve decided to round up the top 20 men and women who are making the big decisions in the telecommunications industry these days, but we’re ranking them by the measure that really matters: how their employees feel about their leadership. We’ve used up-to-the-minute CEO ratings fromGlassdoor.com to put together this list of the highest ranking telecommunications CEOs you could hope to work for, ranked by previous and current employees. In putting together the list, we only chose CEOs who had more 5+ recent employee reviews/ratings, and who had earned a minimum CEO approval rating of 70%. The CEO ratings shown below are dated as of 10/27/14, and may change.
