(CNN.com) — One by one, the office Casanova dated several of his female co-workers at a small technology firm in California. His dating escapades turned public — and problematic — when he chronicled his opinions of the women on Facebook. He called one co-worker “a snore” before the updates spiraled into explicit comments. When his manager learned about the Facebook updates, chaos ensued. One woman who was the subject of his offensive comments believed she had been sexually harassed at work.
