Ask any 25-year old engineer what Labor Day means to him or her, and you might get an answer like: it’s the surprise three-day weekend after a summer of vacationing. Or it’s the day everyone barbecues at Dolores Park. Or it’s the annual Tahoe trip where everyone gets to relive college. Or simply, it’s the day we get off because we all work so hard. And while founders and employees in startup land certainly work hard, wearing their 80-hour workweeks as a badge of honor, closing deals on conference calls in an air-conditioned WeWork is a far cry from the backbreaking working conditions of the 1880s, the era when Labor Day was born.

Labor Day was declared a national holiday a few month later in an effort to mend wounds and make peace with a reeling and restless workforce (it also conveniently coincided with President Cleveland’s reelection bid). The Battle is Not Yet Won Today in Silicon Valley, this battle for fair working conditions and a living wage seems…
