Can a manager delegate manager specific duties to their employees without offering fair compensation or without making the employee aware that this extra work wont lead to extra compensation and having the work be optional? If not, do workers have the right to refuse these extra duties free of consequence?
To be clear I'm aware that proper delegation of duties is a managers role. But if there are duties specific to a manager or assistant managers position, can they order an employee to take on that extra work out of scope without the right to refuse?
To me it seems like manager work without manager pay. If an employee is given extra duties not list in their job description then I'm of the opinion that those duties should be optional and all aspects should be fully disclosed, ensuring the employee is aware they are choosing to take on extra work without compensation and have the right to refuse.
Are there any legal grounds or workers rights laws in place that reference this?
