Department of State Inclusivity Act of 2020 This bill establishes measures to promote diversity at the Department of State, and it offers a formal apology from Congress for encouraging policies at the State Department such as the Lavender Scare, which resulted in the wrongful termination of at least 1,000 people for alleged homosexuality. The bill establishes a Chief Diversity Officer at the State Department to lead inclusion initiatives, support recruitment of a diverse workforce, recommend trainings on inclusivity, and ensure continued compliance with applicable laws and regulations. The bill requires the State Department to report certain data regarding the diversity of its workforce; conduct interviews with current employees, and exit interviews with separating employees, to receive feedback on workplace policies, professional development opportunities, and other issues affecting diversity; expand anti-harassment, antidiscrimination, and implicit bias training and make such training mandatory for certain individuals; develop a pilot program to use gender-neutral terms in evaluation forms; review employee terminations to determine wrongful terminations based on sexual orientation and issue a report on the findings; establish a Reconciliation Board to contact an employee (or family member) improperly terminated during the Lavender Scare and offer to change the employee's record; establish a board to address issues faced by lesbian, gay, bisexual, transgender, queer, and intersex Foreign Service employees and their families; and report on which countries refuse to issue spousal visas for Foreign Service employee spouses due to sexual orientation and recommend how to address this issue.
