HR Records Management and Privacy
HR Records & Privacy
HR records management and privacy, explained
- Collect less · Use only for the stated purpose · Destroy after retention ends
- Key points: access control and separate storage for sensitive data
- Neglected records of former employees and rejected applicants are the most common weak spot
Once this practice takes hold, the questions HR staff ask change: from 'Which folder was that file in?' to 'Who can see it, and until when?' Even one performance results file gets tiered access: some people open the original, some see only the grade, and some see nothing, and every file carries a scheduled destruction date. Because the unit of work shifts from holding data to managing who may use it and for how long, real change only shows up when you start with HR forms and folder structure.
HR records fall into three tiers: general personal data such as name, contact details, and work history; sensitive data such as health, medical history, and union membership, which requires separate consent; and unique identifiers such as resident registration numbers, which may be collected only with a legal basis. A resident registration number cannot be collected without a legal basis, even with the individual’s consent, and that is what sets it apart from ordinary items. There is a basis for year-end tax settlement and four major social insurance programs filings, but no reason to collect one in advance at the job application stage. Retention periods vary, too. Some documents, such as the worker roster and wage ledger, must be kept for three years under the Labor Standards Act, whereas rejected applicants’ documents carry no retention duty and are meant to be destroyed.
The most common mistake in practice is thinking 'we got a consent form at hiring, so we are fine.' A blanket consent form does not justify use beyond the original purpose. The moment a résumé collected for a hiring process is reused for an experienced-hire offer years later, or health checkup results are passed along as input for department placement, the purpose has been exceeded. The second is the habit of keeping former employees’ files indefinitely because 'a lawsuit might come up later.' Incidents usually start in old files nobody was watching, and once those turn out to be records that should already have been destroyed, the company has no defense. Data you have removed cannot be leaked, which makes removal the surest safeguard. The law and the security-measure standards may be amended, so please check the latest requirements.

Sensitive information and unique identifiers carry separate processing requirements.
This is the story of Company A, an auto-parts manufacturer with 240 employees. Three HR staff share a single drive, and it came to light that after a first-half reorganization moved 12 team leaders to new roles, they could still open the performance spreadsheets of their former team members. At the CEO's direction, an eight-week cleanup began. (Hypothetical example)
- The HR head opened all 314 folders on the shared drive one by one and found 68 files mixing performance ratings, salary contracts, and health screening results. Eleven of them were named 'final_really_final,' so just checking their contents took two days.
- While building the collection inventory, the team revisited the job application form and found that permanent address, family members' occupations, and home ownership were still on it. The recruiting manager admitted, "We've been copying a ten-year-old form," and 13 of the 31 application fields were deleted.
- We rebuilt the access permissions with the IT assistant manager. The payroll folder is open only to the HR head and one payroll officer, original evaluations to the HR head alone, and accounts are split so team leaders can open only the files of people currently in their own department.
- We moved health checkup results, disability documentation, and medical certificates for work injuries into a locked folder accessible only to the occupational health officer. Six certificates kept "because of an old work injury" had no basis for retention and went straight onto the destruction list.
- They posted a retention schedule and set destruction dates. Employee registers and wage ledgers are kept for 3 years, while unsuccessful candidates' documents are destroyed immediately after selection ends, and a recurring event on the shared HR calendar triggers destruction in the first week of each quarter.
- Eight weeks later, 41 of the 68 files containing personal information had been destroyed and 27 moved to permission-controlled folders. Accounts with access to the files dropped from 26 to 7, and in the second-half review cycle, no rating file was emailed around.
