Payroll

I am in the state of California and I would like to know whether it is lawful for a company to change the payroll cut off days for nonexempt employees to accommodate the staff processing of payroll? The stated payroll cut off days in the handbook are the 10th and the 25th of the month. However, the company several times a year changes the cutoff date to the 9th, giving very short notice of this change as well as making the payroll check shorter for that particular pay period which has a negative impact on employee finances.
