So at our job, our business pays us a double time pay if we work 7 days in a row during a pay period, however we just got our paychecks in and it does not show that we received any double pay whatsoever, looks like all of the double pay hours that we would have gotten were turned into regular overtime hours. This is despite the fact they told us we would get double pay for working Saturday and Sunday like it has been for the last couple of years. According to one of the employees I work with they said they had got an email a day ago saying that they will no longer be giving out double pay. Is it legal to change your hourly pay rate after you had already worked those hours without prior notice of the change?
