There's a scene in Friends where Monica mocks Rachel, saying 'I love Ross... I hate Ross...'. It's one that stuck in my mind when I thought about our love/hate relationship with work, too. We are often either smitten or ready to resign - a constant see-saw, often involving moaning about our manager or company.
Whatever level we work at, and whatever we do, there won't be a week that goes by (or even a day or hour) when we don't say something about not liking where we work, or moaning about a task we've been set, or a particular colleague.
