Attendance patterns: compare context and arrange a fair follow-up
A small contractor sees more absence days on one crew and considers posting a named attendance table in the trailer. That crew also has more people and more scheduled days at a distant site. The superintendent needs a comparable planning picture and a fair follow-up before deciding what the pattern means.

Use attendance records for an approved purpose and compare the opportunities to attend, not raw counts alone. The federal Office of the Privacy Commissioner identifies attendance reports as employee personal information and stresses limited, necessary collection and access. Its page distinguishes federal employee jurisdiction from provincial rules. Confirm the law, agreements and employer process that apply; this lesson does not establish leave entitlements or discipline rules.
Build a cautious planning picture
- Confirm the record's purpose and custodian. Work with the responsible HR or employment adviser on what may be used, by whom and for how long. Use existing authorized information where suitable. Do not create a public named calendar, collect diagnoses or assume a small-crew summary makes individuals unidentifiable.
- Make the comparison comparable. Define the period, scheduled worker-days and consistent record categories. Separate authorized leave, changes in roster and other relevant context according to the actual process. Explain incomplete records. A larger crew can have more absence days while a similar proportion of its scheduled attendance is affected.
- Treat a pattern as a question. Note whether it aligns with travel, task changes, notice arrangements or other work conditions, without assuming that alignment proves a cause. Avoid labels about Mondays or particular supervisors. Check the underlying records with their responsible custodian before drawing conclusions from a coloured chart.
- Use a fair private follow-up. Arrange the appropriate conversation and explain the relevant call-in or return process accurately. Refer leave, accommodation, medical, grievance or disciplinary matters through the employer's qualified process. Ask about controllable work arrangements without demanding private reasons on a crew improvement board.
- Review a suitable response. Record an authorized work change, owner and review point where evidence supports one. Monitor staffing readiness and comparable records without promising fewer absences. Retain uncertainty and changed roster context, and apply the approved access, retention and safeguarding arrangements to the information.
Common mistakes
- Comparing raw absence totals without scheduled worker-days.
- Publishing named patterns as an improvement board.
- Treating correlation as proof of cause.
- Using a planning lesson to invent leave or discipline rules.

Check your understanding
Six absence days look twice as high as three. What must you check before deciding one crew has a worse pattern?
