Business siders including HR, marketing, sales, product, execs, managers etc ALL universally don't work Fridays. They (used to) come in for a couple hours then "bunk off" to the bar for lunch and happy hour (starts at 3). I find it ridiculous that engineers actually do work on Fridays, much less Friday after 3pm.
