(or maybe just boss-type-men)
When you get to the office several hours after your employee and say to her “Wow. Looks like you had a rough night” it does not actually translate to “Thank you for working until 2 a.m. last night (this morning?) and coming back this morning to work on this ridiculously tedious and ginormous project”
Okay in his defense he did say thank you (later). But still.
