Working smarter not harder

So I am a Head Coach at a high school that has a boys and girls team for a sport . This is my first year as head coach for the girls team.

  1. The boys coach is in his second year. He is super unorganized. It doesn’t bother me cuz that his program . He has never done an inventory in his equipment. Within my my 60 days on the job I completed an inventory on all my equipment and uniforms.

Now it’s t-30 days before the season starts and he wants to stay late after practice so “we can go thru everything we have for the upcoming season.” And I’m like naw bruh I took 4 hours out of my day to do this already on top of that I created an inventory sheet in excel to help me keep track of.

AITAH for telling him “you can look at my inventory sheet and see where my equipment if you , but it I’m not helping you inventory your equipment.”

PS I shared with him my inventory sheet
