Margarita Zayas was an ultrasound technician employed at Rockford Memorial Hospital from November 1999 to April 2011. Though she received positive work evaluations as recently as 2008 and 2009, she was terminated because of repeatedly sending disrespectful emails to her direct supervisor Larry Griesman.
Over the course of one year, Zayas sent a series of insubordinate emails to Griesman, despite several meetings and warnings. Even after Zayas received a formal written warning, she persisted in sending emails that "were perceived as negative, unprofessional and disrespectful towards her managers and peers." Because she did not heed her employer's warnings, she was terminated in April 2011, at the age of fifty-five, the oldest ultrasound tech at Rockford Memorial Hospital.
