employee will be charged with a crime because they did not volunteer to perform an advertised workover?

You've cited cases that say it is illegal to refuse overtime.  How does that apply to individuals?

A company representative sends out an email offering a workover available at Base "A".  Do you charge all of the employess that don't volunteer to take it, or just one of them?  Which one?  How does this apply to actual individual employees?

This is why you're not a lawyer.
