Somewhere, somehow, someone's gonna be...

...fired.  Not what Johnny Mercer had in mind, but the Iowa Supreme Court carries a different tune; that when an old immovable object like a wife is met;

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.

Then it's like any other contractual agreement, and either party is free to end it.
