"Aggretsuko," who was introduced in Japan in 2015 and debuted on Netflix in April, humorously commiserates with office workers on the frustrations they face. The sweet Aggretsuko explores the toll that a toxic work environment can take on people as well as the release that is screaming metal karaoke about your work woes. Some of the songs include lyrics like "Lightning, grant me your vengeance," "Wake up in the morning and do it all again" and "Choke on my rage!" The Den of Rage, which is open from 11 a.m. to 6 p.m., Friday through Sunday at the Upper East Side Barnes & Noble, offers a chance to rage/photo opp with Aggretsuko herself, an exclusive T-shirt design, limited edition merch and free bookmark giveaways and a gift with any Aggretsuko purchase. The pop-up is celebrating the launch of a new book, "The Aggretsuko Guide to Office Life," ($13.46) which offers tips on how to deal with office holiday parties, avoid your colleagues outside of work, dodge oversharing co-workers, and how to "rage," or expel your pent-up anxiety. Other tips include how to forge a relationship with a frustrating boss, how to master your commute and avoiding elevator situations as well as manipulative co-workers. The show has been picked up for a second season in 2019 on Netflix. If you go: The event is free and runs from 11 a.m. to 6 p.m. Nov. 30 - Dec. 2 at the Barnes & Noble at 150 E. 86th St. By Shaye Weaver firstname.lastname@example.org @shayeweaver Shaye has been covering worth-your-time events and things to do around the city for amNY.com since September 2017.
