So my mom works at a company that is busy during the winter and not so busy during the summer(they sell propane and heating supplies) so they have a lot of part time and seasonal employees during the busy season, my mom being one of them. There is another seasonal employee, let's call her Amy, who is using all her pto to take off most of March. Today my mom had a meeting with her boss, and the boss informed her that they will be telling Amy not to come back after her vacation, so that my mom can take on all of Amy's current job responsibilities and become a year round full time employee. Amy has not been informed of this yet. Is it legal for my mom's boss to discuss someone else's employment status with my mom? Also do you think my mom should warn Amy that she's getting laid off?
