What does the idiom “poison pill” mean?
Definition: A provision or feature added to a measure or an entity to make it less attractive, an undesirable add-on
Example: The company’s offer contained a poison pill—increased work hours—so that workers would reject the offer when they voted on it.
Note: This term originated in the financial world—a poison pill is a provision added to a company’s stock to discourage hostile takeovers. Lately it is being used more broadly.
