Stars are relative to your manager level. Since you're new, you would level up very fast initially, allowing you to purchase better staff. Your existing staff, which are now lower leveled relative to you, will see a decrease in star ratings. Their stats have not actually changed, though.
From the manual:
Stars indicate skill relative your current level. So, if you're currently level 10, a level 10 driver or staff would be displayed as 5 stars. A driver or staff that's half your level will have 2.5 stars and so on. This is why, as you progress through the game and level up, you may see the star rating of your own drivers and staff decrease. Their skill level has not actually changed, but your level as a manager has increased relative to them and you are now in a position to get higher level drivers and staff. The star rating acts as a clear way of indicating this to a manager.
Enjoy your time here. :)
Ahhh that explains a lot thanks!
I have another question.
My finances are getting lower. I lose more money, my price money and earnings are 2 mil and costs per race about 2.9 mil.
I see a lot of people struggle with this..
