Anecdotally I'd argue that it's not just "plenty", but the majority of people who only work one single job barely and/or pretend to work. I regularly see Principal+ engineers, VPs and Directors waddling around looking important or just staring at their monitors with a glazed over look.

Most corporations don't need nearly as many employees as they actually have, so if you can deliver exceptional results in 20 hours, why not dedicate the remaining 20 hours to another corp, and double your comp? Everyone wins.

HackerNews dudes claiming they do a true minimum 40 hours per week, every week, forever, of heads-down hard-work are deluding themselves. I really don't understand the overemployment hatred this forum has. There are plenty of folks who really do solid work at 2+ jobs, not half-assing and politicking.

Disclaimer: I am not OE.

When people with no integrity or ethics defraud their employers, "it's life"?

but these people attend too many meetings; the OE ones miss everything.
