The phrase work-life balance became popular in the UK in the 1970s, but the concept has been around for much longer than you might imagine. Apparently it originated as far back as the mid-1800s, when Labour Day (May Day) was established as a public holiday in Australia, with the labour unions claiming that everyone was entitled to 8 hours' work, 8 hours' rest and 8 hours of recreation - a perfect balance. The sentiment is also expressed in the well-known saying "All work and no play makes Jack a dull boy", first recorded in the mid-17th century, but probably going back to Saxon times. The arrows here, pointing in opposite directions, remind us forcefully that work and 'life' should be kept strictly separate.
