The distinction between hostile work environment and quid pro qua sexual harassment is important for determining employer liability. Employers can be liable for hostile work environment harassment caused by a supervisor, other employees, or by third parties (e.g., customers and vendors) if the employer knew or should have known of the harassing conduct and failed to take appropriate corrective action. Generally, an employer may fulfill its duty to prevent or remedy hostile work environment harassment by developing an antiharassment policy, promptly and thoroughly investigating harassment allegations, and properly disciplining offenders. As the HR Journal discusses, some employers have gone so far as implementing “love contracts” to protect themselves from the fallout of romances at the office.
