A dentist acted legally when he fired an assistant that he found attractive simply because he and his wife viewed the woman as a threat to their marriage, the all-male Iowa Supreme Court ruled Friday.

The court ruled 7-0 that bosses can fire employees they see as an “irresistible attraction,” even if the employees have not engaged in flirtatious behavior or otherwise done anything wrong. Such firings may be unfair, but they are not unlawful discrimination under the Iowa Civil Rights Act because they are motivated by feelings and emotions, not gender, Justice Edward Mansfield wrote.
