No pay for late timesheets

ffpm272@yahoo.com

This has probably been discussed in the past but I am unable to locate any discussion on it.  The local government I work for has been withholding paychecks for employees that submit their timesheets late.  They end up getting paid the next payday (2 more weeks) which then causes them to pay more taxes.  I keep telling them they cannot do that but it has fallen on deaf ears.  Any help locating specific language in statue would be appreciated.  They seem to think they can do whatever they want without any consequences.
