Excerpt from this article:
…more and more, the sick day is disappearing from the office vocabulary, even as we hit peak flu season. Once, a sick day was just that — a day away from work to focus on recovery (or at least pretend to: Think “Ferris Bueller’s Day Off”).
But in recent years, it has become something murkier in definition and more reflective of our highly competitive, 24-7 work lives. The shifting definition and expanding mobility of the office — thanks to remote work and the rise of contractors in the gig economy — is also making the sick day somewhat passé, at least for some jobs.
“Even if you take a sick day, you’re still emailing in the morning, checking in later in the day,” said Kit Warchol, the head of content marketing for Skillcrush, an online coding school. “It’s become more of a norm to write to your colleagues and tell them you’re working from home.”
