Dan Harmon, creator of the NBC show Community and co-creator of the Adult Swim animated comedy Rick and Morty, has been publicly called out by Megan Ganz, a former writer on Community.

Harmon took to Twitter on Monday to name 2017 the "Year of the Asshole" and explicitly included himself as one of the reasons for doing so. As a goal for the year, he went on to hope that 2018 will be the "Year of the Not as Much of an Asshole."

But Ganz was not about to let Harmon off the hook so easily. She replied to his tweet and urged him to be more specific, suggesting she had receipts for why he deserved his "asshole" title.

Soon, the conversation evolved into a public discussion about power dynamics in the workplace and how, no matter how repentant or apologetic someone may be, workplace abuse of any kind can leave lasting wounds.

Ganz, who has also written for Modern Family and It’s Always Sunny in Philadelphia, wrote six episodes of Community, the show that starred Alison Brie and Donald Glover, among others, during its seven-year run.

Harmon apologized for his "selfish, childish shit" and said he has "felt sick about it." While neither Harmon nor Ganz explicitly mentioned what happened between them, it's clear some form of harassment or abuse of power took place. 

Although it doesn't seem the two came to any concrete conclusion, the exchange was a relatively civil dialogue between a man who clearly abused his power and a woman with whom he worked. And on Twitter, at that. That’s pretty remarkable, if only because it illustrates how far we still have to go when it comes to resolving power dynamics in the workplace, especially between men and women.
