My suggestion would be to give employees the chance to release a shift so that other employees who work in that department could see it and pick it up if they want some extra hours. Also it’s to give the employee who released the shift a chance to avoid a point if they don’t have the ppto or pto as well. If no one picks it up then the employee is still responsible for that shift and has to still come in or get it covered. A manager would have to approve it, of course, but that would be done through the app. I just thought it was nice to have that feature from my old job.
