"researcher access to confidential records adds to the vulnerability of workers who participate in workplace studies. inappropriate release of identifiable private information could adversely affect a worker's retention of a job, insurance or other employment related benefits. to avoid or minimize these risks, the study design must include adequate safeguards to protect the confidentiality of the information collected. a plan for the proper management of study data and records should clearly define: "

I believe the answer is:

- Who will have access to the data.

Determine who had the authorization to access the data in order to prevent the risk of alteration.

- If the study results, if any, will be included in the employee's personnel records

- If personal identifiers will be retained and used in the data analysis.
