Once you develop your own employee filing system, maintaining your employee files should not a burdensome task. Many employers use the time involved in performance evaluations as a good time to update each employee’s employee file and any information you may need. For example, perhaps you have a new company policy that the employee needs to sign. Also, make sure that the employee’s file contains all relevant and up-to-date information.
You should create a blank check-sheet for each employee’s file and use this to double check that all the information is there whenever you’re updating your employees’ files. And remember, generally only individuals with a "right to know" should have access to your employees’ personnel files. States generally provide different laws on who may view employees’ files. Check with your state laws or a local attorney for more information.
