I like Sheryl Sandberg... a lot. Of course, there's lots to admire - the extraordinary career, the fundamental fairness of her ideas in Lean In and, above all, her unblinking honesty.

It was this honesty that underpinned her heartfelt message...

Colleagues. Co-workers. Peers. Whatever you choose to call them, there's no doubt that they form an important part of what makes your working day tick.
