Once upon a time, the idea of a five day working week was something rather strange. Now, with our five-day week the norm, the concept of the four-day week probably seems like a step too far for many.
But it's a hot topic that hits the HR news feed almost daily - take, for example, the worker who sued her company and won damages of £100,000 when she was sacked after asking to work a four-day week. Marie Raphael had requested reduced working hours after suffering a stroke, but she soon found herself accused of misconduct and was dismissed.
