Our OKlahoma company changed is PPE dates.. We pay biweekly, have mostly exempt empl, we gave 3wks notice, paid empl for one week then went to the new PPE cycle. Is there a source that says how much notice should be given, or what kind of implications there are to changing the PPE dates?

I have an associate that says that they are going to be shorted by one week of pay this year because of the change. (they aren't really going to be shorted, but one of our normal 26 PPE is only one week long and the other week goes into wages for next year since the change). .... surely there is something that allows for companies to change their PPE dates, I just cannot find it.
