Pros
Extremely positive brand reputation, enthusiastic co-workers, relatively easy hours, decent benefits. PBS (I'm referring to the main headquarters in Crystal City) is a great place to start a career in media. If on the right team, you get a fair amount of autotomy and you can feel proud to be creating a quality product. Most co-workers are easy-going and good natured.
Kontras
Confused/muddled overall strategic direction, weak upper management, absurd waste in certain areas (e.g. bad content and platforms) but penny-pinching in others (e.g. salary). As the rest of the media world is trying to rapidly innovate in a changing landscape, PBS always feels a few steps behind. Well-intentioned managers with poor strategic vision tend to delay and ruin projects. Lots of mid-career folks just parked at an easy job while raising kids. HR seems to ignore management quality issues that have led to high turnover rates in certain departments.
