Pros
Discovery has great brands that most people love. The work is often challenging and rewarding. Despite Discovery's strength, there are many areas that it needs to development, particularly in the digital space. This presents tons of opportunity for those who work hard and are good at what they do. Most people are relatively easy to work with, and there is very little office politics or drama.
Cons
Because the culture is less cut throat than other places, people remain in positions even if their performance is mediocre or poor. While I like the more laid back environment, I do think there needs to be more accountability. Zaslav has introduced a culture of accountability at the senior executive level, but it has just beginning to make its way to the rest of the ranks.
