Ugh summer school sucks

so i’m working at an elementary school next week-july 8.. It’s a bus aide which means i’ll be on the bus in the morning and then after noon to pick kids up and drop them off. welll i been on that bus before and IT DOES NOT have air conditioning . And it’s going to be 100 degrees or more this summer so i’m very scared we will suffocate ? do you think they will switch buses and get another one with air conditioning?????? because i have anxiety attacks and afraid i’ll pass out ???
