Youjo Shachou

Maybe if Retsuko had Najimu for a boss instead Ton, she'd be less angry. Not only are these shows similar in setting and art style, but I'm pretty sure Youjo Shachou's ending theme is a direct reference to Aggretsuko.  

Both are short animes, where surrealistic or random comedy acts happen every second of it. I must say, both of them are enjoyable experiences if you want just to chill and have small laughs.
