Communicate With HR Without Raising Red Flags
HR will not override your boss
In most matters, like layoffs and probationary periods, your supervisor will always have the upper hand. Human resources monitors the goings-on in the department, but cannot override many of your supervisor’s decisions, unless there is a big issue at hand, like sexual harassment or illegal practices. So don’t go running to them to force your boss’ hand on something because it’s probably not in their jurisdiction.
