So the same question for your company. Why is the only during the summer? A staggered every other Friday off has always been something I’ve hoped would become mainstream year round. It isn’t that progressive of a thing to enact since its staggered/every other.

Generally, we work from home all Fridays, so you have to handle your meetings and email, but there's still flexibility. The summer fridays are nice because you are completely off, no expectation of availability.

It's a little silly to only do in the summer, but it's still a nice perk.

The most people get used to it, the more I would expect "Thursday" to become the new Friday and you should expect to quickly end up losing the benefit of that additional day off as laziness takes over.

My company implements an optional every other Friday off. Somewhat surprisingly, Thursday hasn’t really become the new Friday. In fact, the people who choose to work the full 5 days tend to get more work done on Fridays, since fewer people are around to interrupt them. The people who take those Fridays off are generally happier and still pretty productive on Thursdays.

If people didn't want to work at all this might be true (at least if Friday off was widely implemented). But generally that doesn't seem to be the case. Unemployment seems to stress people, and most people seem to prefer vacations that are 2-3 weeks at a time, even if they could take more. So if you offered people to come in whenever they want they might be there more often than you expect.

Wouldn’t people be comparing to their peers outside of work? Most people don’t get any Friday’s off. It would be pretty wild to start wanting Thursday off so much when no one else is getting Friday off.

I’m not sure lazy people care which day of the week it is.
