Monsters at Work begins the day after Henry J. Waternoose III's arrest, with the Monsters, Incorporated factory making the transition to laugh power. Tylor Tuskmon, a recent Scare Major graduate from Monsters University, having previously received a letter of acceptance from Waternoose to be a scarer at the factory, is excited to work at the same company as his idol Sulley. However, Tylor is devastated to learn that the company is no longer in need of scarers, and he is reassigned to work as a mechanic on the Monsters Inc. Facilities Team (MIFT). Meanwhile, Mike and Sulley encounter the trials and tribulations of running the company.
