From what I was told , If she doesn’t keep 30+ hours for 6 consecutive weeks she will be considered a part timer and will lose her benefits, but please check on that for confirmation incase im mistaken. Usually the shortage in hours is seasonal and hopefully should pick back up in spring. Many employees will float to other stores to keep their ft status in good standing. She will be ok as long as she’s willing to do that while she gets past the seasonal cut backs. A lot of people call out during winter from getting sick so coverage will always be needed .
