In Skuse v. Pfizer, the Supreme Court upheld Pfizer’s arbitration clause, which the company sent via email to its employees. The Court ruled that Pfizer’s communication informed Skuse that if she remained an employee with the company for more than sixty days after her receipt of the communication, she was deemed to have assented. Moreover, the communication “clearly and unmistakably” explained the rights that Skuse would waive by agreeing to arbitration.
