Final answer:
The disadvantage of a mandatory arbitration clause in an employment contract is that it can limit employees' access to the courts for discrimination cases, potentially resulting in unfair outcomes and limited legal precedent in equal employment matters.
Step-by-step explanation:
The primary disadvantage of a mandatory arbitration clause in an employment contract, particularly concerning Title VII of the Civil Rights Act of 1964, is that it can prevent employees from having access to the courts for discrimination cases. Mandatory arbitration requires that disputes be resolved outside the judicial court system, which often means that an unbiased jury will not hear the case, and limits the possibility for broader legal precedents to be set in the pursuit of equal employment opportunities. Moreover, mandatory arbitration may impose limitations on the collection of evidence and may involve arbitrators who are less familiar with employment law than judges, resulting in potential disadvantages for employees seeking to assert their Title VII rights.
