As a salaried employee, part of my job responsibilies include being on-call 24/7 to answer questions and handle issues that arise when I am not there. Am I required to use PTO when I am not in the building and continue to take call at home? I do not have scheduled shifts and there is no one readily available to cover my on-call responsibilities when I am not able to.
Iowa is a right to work state which means you can be terminated for any reason, good reason or no reason at all unless you have a contract of employment or are covered by a collective bargaining agreement. What does your employee handbook have to say about the subject?
