How does the soft check on workers limit work?

I've noticed that the first soft cap is about 100$ so i guess that having a balance that's more than 100$ will increase my workers limit. What happens if my balance goes to 90$ afterwards? Will my limit be lowered? What will happen to active workers?

Solution

The soft limit just checks your balance at the time of the upgrade, if you do fall below that balance at another time you will not lose access to the upgraded workers count.
