Societal pressures used to make it relatively easy to take time off: you couldn’t go shopping when the shops weren’t open, even if you wanted to, or work when the office was locked. Besides, you’d be much less likely to skip church, or Sunday lunch with the extended family, if you knew your absence would raise eyebrows. Now, though, the pressures all push us in the other direction: the shops are open all day, every day (and all night, online). And thanks to digital technology, it’s all too easy to keep on working at home.
