We (in Germany) had a day where we were supposed to join one parent at work and yes, German has a word for it: Schnupperpraktikum (literally snuff internship)

It was in the year (8th grade I think) where we did a student internship and beforehand he did a one day internship at one parent.

Now that I’m in the workforce, it happens that colleagues bring their kids to office during holidays or preschool kids but we don’t have a day for that.
