While EEOC guidelines for managing sexual harassment prescribe a strong sexual harassment policy and aggressive remedial action following complaints, a communication approach suggests a need for a more complex understanding of sexual harassment as diffused throughout an organizational culture. The present case study uses a sensemaking approach to explore the response of members of an academic department to an alumnus donor's serial sexual harassment of three of its members. Sensemaking proceeded through three phases: the phase of discovery, the debriefing phase, and the dispersal phase. Insights into the role of humor, white men, shared experiences, and responding to sexual harassment are discussed.
