I thought hybrid meant that two days per week everybody goes to the lab, the rest of the days are remote.

Yes, but if everyone is out three days a week, in pretty much every meeting, at least one person is going to be out, making nearly all meetings virtual by default.

No, I mean monday and tuesday everybody goes there. This is how we are planning to do it from september and most people seem happy (especially new recruits).

Ah ok. Yes, this might work better for people.

at the end it may as well be just one day per week. The "pizza seminars" used to be a happy routine before the pandemic, and even colleagues who love WFH want to recover that.

I agree for internal meeting, but in my industry where external meetings are a huge part of my job, it's meant way less driving to meetings for me which has been a huge boost to my productivity levels.

Oh, my complaint is more that I am now Zooming in an open concept office with others talking right beside and behind me. I am fine with virtual meetings.
