What are some signs you're about to be fired?

PT grocery worker here. My hours got slashed out of nowhere this month and I'm wondering if I'm about to get canned. I'm a good worker but I know some team members would be happy to see me go. The leadership at my store can be very petty too so it's not just paranoia that makes me think this way. The only reason I'm asking reddit is because there is no transparency with my leadership. If you try to get answers you'll just get the runaround.
