I realize Missouri is a right to work state, but I have a question concerning required hours to work. I am required to work shifts that allow me only 4 hours of sleep between them. Is this legal? Is there any law that prevents an employer from demanding outrageous hour requirements that would force an employee to quit: I'm thinking an employer doesn't want to pay severance for firing an employee so they require crazy hours and thereby make the employee quit. Is there any law in Missouri that prevents employers from demanding 40 hours of consecutive work without a break? If there are laws that prohibit such an action, please cite the mandate in your answer.
