How long does an employer need to keep job applications on file in missiouri?

They can keep resumes for as long as they want, some toss is out right when they get it because they aren't hiring, as well some keep them for years just in case.

If you are a government contractor, or if you employ more than 50 individuals, you must comply with government Affirmative Action/EEO & Veterans laws. If this is the case, you have to keep resumes on file for the Department of Labor for at least 3(?) years. This is to ensure that if the DOL does an audit on your business, they can see that you are hiring a fair mix of ethnicities & sexes that apply for positions with your company.

If you hire an employee and then terminate them, you must keep their file with a properly filled out I-9 form, for at least 3 years after termination.
