Should be on managers to communicate that down. What I typically see though is this coming from the very top, mandated down the line, managers given little info, training, or support for the rollout. And even worse the whole "it's up to each team to decide how to implement" again, no guidance for the manager. Which immediately leads to frustration, disengagement, and inconsistency across the company.
There should be better communication for sure, and for the record I’m against this RTO stuff in general.
But if there is any kind of RTO in place, anybody with half a brain can assume the intent is not to have people drive to the office, swipe in and out, and then immediately leave. That’s just dumb and they know better.
