People around the world are different, companies are structured differently, work cultures vary. We should not try to "homogenize" everything. And as such, why use data from a global set to apply it to a local set?

If teleworking works for your company, great keep doing it! If it doesn't, don't do it. And lets not demonize when a company makes a decision that is right for them in their particular case.

For our company, we've made the decision to not allow teleworking, and it is only approved temporarily on a strict case by case basis. I think it has helped our work culture and productivity over the many years.
