We have a required day in office and seeing inconsistent attendance. We have a dispersed team with managers who are not onsite with their employees.  It’s impacting others willingness to show up. We haven’t implemented tracking badge swipes or disciplinary action. What is your company strategy to ensure attendance? Are you implementing disciplinary action?

Indeed, first understand why people don't come to the office, what is holding them back (if anything). Then reinforce the message why you are implementing this; interaction, face to face activities, team work etc etc etc. Managers are responsible to stimulate this policy and it has to be a company request, not HR trying to get people back in. This is not an HR topic it is a leadership one. Else you will end up policing which only works counter productive ("HR told me to come to the office") So first listen, then involve managers

Instead of policing, I recommend to
- highlight the WHY (why is it important to come to the office - WIIFM?), and
- hold managers accountable for both their team’s and their own presence, as required. This applies across ALL levels of hierarchy.
