Is it legal for my employer to put only 40hr one my salaried paycheck when he requires 42.5 hrs?

I am a salaried employee and recieve no overtime pay regaurdless of hours worked. In fact my employer required 42.5 hours min per/week instead of the normal 40 hours min week. This I know is ok but what I'm wondering about is the paystub information.
My employeer only reports the work week as 40 hours instead of the 42.5. Is this legal? I would think accounting records need to be honest but I also know if I would say 50 hours in a week, that doesn't have to be put on a saleried check.
is this extra 2.5 hours a lunch break? if so then it is fine because you are not working 42.5 but 40. It also depends on your salery contract... if you agreed to X per week then that is what you get if you agreed to X for 40 hour week then that is what you get and you are owed the overtime not only on your stub but in actual dollars.... sounds to me lik eyou are working 8 hours a day plus a half hour for lunch.... Did you try asking your employerwhy this is? or are you just assuming that they are cheating you ? i would ask them about it... if you do not get a responce that sounds factual then you can take it to the next level which i would think is you local labor board...
You should be getting paid for the work you do. If the extra work you are doing is overtime you should be getting paid extra


Answers:
Have you asked about it? It could be something as simple as the payroll department doesn't really know your hours so it's defaulted to the usual 40.
