Manpower Corporate Office Headquarters

I work for the festus office and i have worked for them for over a year and i am not getting holiday pay and i know that i have more than 1800 hours and when i get my check stubs emailed to me they do not show the hours that i have worked and they should since i was told by the office that i have to keep track of my own hours which is crazy the company that hires these employees should keep track of their hours not the employees. I will be contacting someone about this
