Getting burnt out

I work at a relatively small Walmart, our OGP department is small. We keep getting busier and busier, and more stuff keeps getting added to our workload. At this point, we are pulling other departments to help daily. We were #1 in our market for the longest time and now our numbers are absolutely horrible. Everyone is losing motivation. Coaches only care about how we look for market and never check in to see how we're doing. We're all doing the jobs of 3 people to keep things going every day. We absolutely do not have enough people on our team for how busy we are, and a lot of the people on my team spend way too much time sitting around talking and wasting time. I constantly think about just jumping ship but there aren't good jobs where I live.
