• Robinson v. Shell Oil Co. (1997). Title VII’s retaliation clause protects former employees as well as current employees from unlawful retaliation.
ROBINSON v. SHELL OIL COMPANY 117 S.Ct. 843, 136 L.Ed.2d 808 (1997).
Shortly after being fired by Shell Oil Company (“Shell”) in 1991, Charles T. Robinson, Sr. filed a charge with the Equal Employment Opportunity Commission (“EEOC”) claiming discrimination based on race.’ While that charge was being processed, Robinson applied for another job.’ Seeking an employment reference, the company to which Robinson had applied contacted Shell. Robinson believed Shell provided a negative reference to the potential employer in retaliation for filing a discrimination charge with the EEOC. Robinson thereafter filed an anti-retaliatory discrimination charge against Shell with the EEOC and sued in the Federal District Court for the District of Maryland.
The Shell Oil case was a big win for former employees.
In any event, employees in the US have a host of legal protections against vindictive behavior on the part of current or former employers.
