Now we have a gig economy where many people are holding down several jobs at once. The whole concept of a 40-hour week makes people under 30 laugh.

We know that people who work without breaks get tired, introduce errors, get sick and miss out on life. Make no mistake: those staff room hammocks are designed to keep you in them on the weekend.

For me, writing started as pleasure that became professionalized, so my relationship to it is a bit sullied. I'm working it out.

There's something about the weekend, even for non-religious people, that feels sacred, so a violation of that sanctified time is almost a betrayal, something blasphemous. The sabbath is the edict to break from work. It was God's call-out to the slave to protect an identity beyond labourer - no production and consumption, just one day a week.

We know that our bodies suffer from overwork and lack of leisure: anxiety, mental-health issues - we're not designed to work more than about 40 hours a week. Our systems wear out and the quality of the work suffers. After 50 hours, it crashes and burns.

If you're in the mood for a blushing art house romance, you'll fall for it, too.

We can do a bit of blaming: the proliferation of devices means we're always at work, always on call, always available. Physically leaving the office isn't a declaration of being off work anymore; your office is in your bag or pocket.
