I worked at a US company that wanted us to put in the extra effort and do work after hours. They tracked this with a summary report of work submitted after 5.

So I worked normally and then I'd sit on all my work and wait until just after 5:15 to submit it all and then leave immediately. I didn't get in until 9:30 or 10 anyway so there was literally no difference except my work was delayed.

They praised our team for all the extra work. They really had no clue.
