The question asked does not fit the provided historical context which covers the 1964 Civil Rights Act, the EEOC, and actions taken to investigate employment discrimination, alongside Phyllis Ann Wallace's contribution to the commission.
The student's question does not specifically pertain to any data analysis or investigation related to an individual's employment history or commission earnings. Instead, the question refers to historical events and legislative acts which influenced employment practices, such as the 1964 Civil Rights Act and the establishment of the Equal Employment Opportunity Commission (EEOC). These actions aimed to protect employees from discrimination and enable the investigation of employment discrimination. Economist Phyllis Ann Wallace played a significant role as she was appointed the chief of technical studies at the EEOC. Her contributions included organizing public and private sector data and guiding other economists in investigations. Furthermore, the historical context of employment reforms is broadened with references to the First Enforcement Act and the formation of a commission for civil service reform during the early 1870s.
