Just Another Day at The Restaurant

Another Day of work we are short staffed. Whats new the same thing happens at almost every restaurant at this time of year. Every one goes back to school and you end up short staffed. How dose this keep happening year after year. It dosn't change!!!!! I am working on my second year of management and I already know how to fix the problem but it is the bosses above me. We're fine we don't need to hire we'll slow down when school starts but we can't even run a simple monday or tuesday shift because the retaurant is short staffed. It takes the area director to come in to make the GM realize we need more staff. Although it dosn't take a big brain to figure out when you only have one cook on saturaday and sunday mornings at a restaurant that is famous for breakfast that we need to hire more staff. How hard is it to continuously hire towards the end of summer to ensure you are fully staffed when school starts back up? Aparently pretty hard since it seems to me no matter what restaurant I've been in it is always done at the last minute after customer complaints rise and every shift is rocky. Although after numerous shift covers and people are where they need to be the shift will sort of run ok but how can we stop the cycle?
