No hours for 2 weeks???

I work in grocery and have closing availability for 5 days out of the week. I don't understand how I went from 20-25 hours to nothing. And we just had so much buisness because if the snow storms in GA! 😩

We got a new grocery manager and ever since my hours just disappeared over the past 3 weeks. We don't have any new hires and I've never gotten any complaints about my work so I don't understand.
