How many of us work or have worked the hours of 9 AM to 5 PM? I would guess quite a few. How many of us have asked why are those the hours we work and are they truly the only preferred (available) option? I would wager to say, not as many.
If you are leading a team, provide your people flexibility and focus on outcomes and performance, over attendance. While in some cases, where one is providing services to clients who walk in, specific hours have to be observed, in majority of others, commuting to work to sit at a desk AND during specific hours, makes little sense and follows questionable logic at best.
Building teams, trust, communication, sharing values is essential, but that could still be accomplished without always requiring dozens, hundreds, perhaps even thousands of people to be in the same space at the same time.
Think about it and break the mold you have taken for granted for so long.
