It's cool to do these to your friends in High school, but I once wasted a good amount of time at work because of an April's fool joke. I already didn't want to do the work so I got really upset to have wasted time doing something boring and useless.
Additionally, the scale of social media can create situations where it wastes everybody's time several times per day... Including on HN.
Feel free to prank your friends, but don't bring it to work or the Internet, please.
There are worse crimes in the world, but it is bad.
Bollocks, and bollocks to the parent hot take. Any moral framework that forbids fun, whether it's because it offends God or "causes people (a tiny bit of) stress", is repugnant to me
You can't even make the (quite bad) defense that people should have known better and it's their own fault for falling for it. The message was 100% plausible.
Not the best way to measure time imo.
My employer gets about 40 hours/week of "work" from me, whatever that might consist of. I cost them $X every two weeks in pay and benefits. It's pretty reasonable to say my attendance in a one-hour meeting has a $X/80 cost to my employer.
You don't need to overcomplicate this. The employment relationship is pretty simple at its foundation: the employer buys the time of its employees.
