Spade will play Tobias Eastmore Jr., the owner's brat son and heir apparent to Eastmore's. Tobias will come into the job with a reputation as a womanizer and failed entrepreneur.
Harris, whose recent TV credits include Fox's "New Girl," will portray Linda, Eve's best friend and coworker. She is full of bad decisions about work and men but stays weirdly optimistic.
Horgan will write the script with her "Dead Boss" colleague Holly Walsh and executive produce alongside Kapital Entertainment's Aaron Kaplan. Ben Taylor will direct the ABC Studios pilot, which will film in Los Angeles.
The "Bad Management" pilot is in second position to Spade's "Rules of Engagement," filling the CBS midseason, so unless the show is cancelled, ABC may have to tap a new lead.
