Annual Leave Request Redaction with anonym.plus

Clear employee names, dates, and reasons from a holiday request before analysis.

In simple terms, PII redaction is the on-device process of finding and masking personally identifiable information in a document before it is shared.

Annual leave request redaction is the removal of personal data from a holiday request so it meets the anonymisation bar in UK GDPR Recital 26. The entitlement itself comes from the Working Time Regulations 1998 — four weeks under reg. 13 plus a further 1.6 weeks under reg. 13A, with notice rules in reg. 15 — and adequate records must be kept for two years under reg. 9. Truly anonymous data falls outside UK GDPR entirely. anonym.plus marks each identifier on your device.

When this applies

Such a request names the worker, the holiday dates, a team, and an optional note. You trim those identifiers toward the Recital 26 bar before any pattern analysis of absence across the year runs.

How anonym.plus handles it

  1. Open the request in anonym.plus on your device.
  2. Local OCR reads a scanned, signed form if needed.
  3. The tool flags names, dates, and the note.
  4. Disable the reversible alias map for true anonymity.
  5. Swap or black out the confirmed items.
  6. Save the anonymised copy locally.

Limitations & cautions

Recital 26 sets a high bar: data is anonymous only if no motivated intruder could re-identify it by reasonable means. Keep the alias map disabled, and check that a small team plus dates does not still single out a worker. A reason note can also carry health data, which stays special category under Art. 9.

Frequently asked questions

When is holiday data truly anonymous under Recital 26?

Only when no party could re-identify it by reasonable means, judged with the ICO's motivated-intruder test. Disable the reversible alias map so no re-link path remains.

What holiday records must be kept?

Working Time Regs 1998 reg. 9 requires adequate records to show the limits were complied with, kept for two years. Those records can be de-identified and still do their job.

Is the request uploaded?
