This is called breaking guarantee.

If you are a line holder, they will assign you flying that adds up to at least 75 hours of credit. If you fly more, you get what you earn. You will not typically be assigned less than 75 hours of credit. If you are not senior enough to hold a full line, you may be awarded less than 75 hours of credit, and they will add reserve days at 4.2 hours of credit per day to add up to at least 75 hours of credit.

If you are really senior, there is a *remote* chance that you can waive the minimum credit and be assigned less than 75 hours of credit. In that case, you will be awarded less than 75 and you will get paid what you credit even if it is less than minimum guarantee.
