I never said it was for everyone, but I suspect people magnify the expected issues a lot.

Everyone knows I won't be here on wednesdays, so we try to arrange things so I'm not a bottleneck during that time. If some really important deadline shows up, I'll just work the one wednesday and take thursday off instead, it's not a big deal. I haven't needed to yet though.

Besides, assuming you're not on a really tiny team, if many parts of your project hinge on one person with no available backup, you have bigger problems related to project management.

This is nonsense, although it may depend on the kind of job you have. For most of us, we don't need to be there five days a week. You can plan around that.

Of course if you have five people in a team and everybody has a different day off, you can never get together, and that may be a problem. This is the same if you and your colleagues work many days/hours out of the office or at home.

Pretty much anything can be made to work if it's planned for and executed properly.

Our dev process required a lot of meetings and interaction. So in order to ensure clear blocks of working time, we used to set aside days as "no meeting days" Some people would take the opportunity to work from home on those days since it was guaranteed they wouldn't be pulled into a meeting. Once you know Sally, Jared and Kaitlyn won't be in on Tuesdays, you plan around it.

It's really not a big deal.

This happens where I work- one of my coworkers is here Monday - Thursday (10 hour days) but takes Friday off. He's the only one with knowledge of a lot of our legacy systems, so a lot of potential work doesn't happen on Fridays. I'd argue that more of us should learn what he knows to avoid "hit by a bus syndrome" but we don't have enough spare man hours to devote to that.

I've had this schedule for about two years now. Never had any syncing issues.

That's why everyone works seven days a week.

Why? Is that much going to happen on Wednesday that can't easily be caught up on Thursday?
