how do i upgrade my staff ?

im so confused where do i hire them ?

Left on the top of the screen you see the icon “stadium”. There you can find the staff departments. To upgrade them you have to click on the green arrow. You also find the upgradecosts and the maintenance costs there.
I hope it helps.

i have nno green arrow theres nothing other than this

I think your board doesn’t allow you to upgrade your staff departments because your financial stituation is bad. That’s why there is no green arrow.
If your financial situation become better you will have a green arrow in that screen.
