Title VII of the Civil Rights Act of 1964 prohibits the creation of a harassing hostile work environment based on the prohibited forms of discrimination, such as discrimination based on sex or race. To hold the employer liable for the harassment, the plaintiff must show that the work environment was so pervaded by discrimination that the terms and conditions of employment were altered. Isolated or trivial occurrences are not likely to be sufficient.
If the harassing employee is the victim’s coworker, that is, someone no higher in the chain of command than the victim is, the employer is liable under Title VII only if it was negligent in controlling working conditions. However, if a supervisor’s harassment of an employee culminates in a tangible employment action, such as a termination or a demotion, the employer is strictly liable under Title VII.
