Lockheed is a big employer in my area. I know people who work 9 hour days and they get every other Friday off. Half the staff takes one Friday and half the other.

Planning is key here. No one is saying the whole office needs off on the same day.

Also work in defense, this is becoming pretty common. Although typically everyone takes the same friday off - that saves operating costs (no janitors or cafeteria on the off day). There's also the benefit that people tend to plan their vacations around the off-fridays, and work the full day on on-fridays. So you don't get stuck at the office trying to solve a problem with nobody to answer your questions at 3 on a summer friday.

I believe the team in question needs to support something in person so they do a split.

I was providing a counterpoint to show that it's preferable having the whole office take off together when that's possible for your business. I don't disagree that staggering the off days could be necessary, but it isn't ideal.

It would not be hard to run a B2B business for 4 days if most businesses had a 4 day work week. That's what the author is arguing for, right?

Why can't we stagger which 4 days people work for fuller coverage?
