Even in Britain, the trade unions tell me that employment contracts have less protection than in the past.

The unions still have a job to do, representing their members' interests to governments and parliaments. And I think collective agreements still have a role, alongside markets and laws.

I had to think whether, after 50 years of hard slog, I was still lucid and fresh enough for the job.

Cinema explains American society. It's like a Western, with good guys and bad guys, where the weak don't have a place.

An important part of my job is listening to diverse points of view at all levels - from Millennials starting their careers... to women at the highest levels of leadership... to my own wife and daughter.

If you have to remind people you're the boss, I don't think you're going to be a very effective leader.

Successful leaders surround themselves with intelligent people.

Few things kill likeability as quickly as arrogance. Likable leaders don't act as though they're better than you because they don't think that they're better than you. Rather than being a source of prestige, they see their leadership position as bringing them additional accountability for serving those who follow them.
