there is a MASSIVE psychological/cultural difference between "well everyone pretty much silently agrees x" and "x is the stated rule." Why not let Thursdays become the new day that people slack off and leave early? Not trying to attack you or anything but why would you undermine an initiative to enforce a better work-life balance? Your response seems pretty complacent/apathetic, which seems irresponsible to me when so many stand to benefit from this change.
