If an absence is due to illness, provide acceptable documentation as described in the policy.

FAQ — First Warning Letters for Absenteeism

Frequently Asked Questions — First Warning Letters for Absenteeism

Practical, HR friendly answers for issuing compliant first warnings and coaching employees to improve attendance.

What is a first warning for absenteeism?

A first warning is a formal written notice that attendance has fallen below expectations. It documents dates, impact, policy references, and the improvement required within a defined period.

When should I issue the first warning?

Issue the first warning when policy thresholds are met or a clear pattern emerges, such as repeated unapproved absences or no call no show. A quick verbal coaching can come first, but do not delay once thresholds are reached.

What must the letter include?
  • Dates and types of absences with timekeeping references.
  • Policy citation and why the conduct violates expectations.
  • Impact on operations or team workload.
  • Clear improvement period and the exact expectations.
  • Follow up date and potential next steps if issues continue.
  • Signature acknowledgment and HR contact information.
How long should the improvement period be?

Common ranges are 30 to 60 days. Choose a window that allows a fair chance to demonstrate reliable attendance while keeping business needs protected.

Can I issue a warning for no call no show on the first event?

Yes, most policies allow a first written warning on the first no call no show because it creates a critical coverage gap. Verify your policy language and any local rules before issuing.

How should I handle medical or protected leave?

Pause escalation and route the matter to HR to review eligibility for protected leave. Keep medical information confidential and separate from personnel files, and ensure the employee follows call in rules while eligibility is reviewed.

Do I need the employee to sign the warning?

Obtain a signature to confirm receipt, not agreement. If the employee refuses, note the refusal on the form and have a witness sign.

What tone should the letter use?

Use a calm and factual tone. Be firm about expectations, clear about the impact, and supportive with resources to help the employee improve.

Can I email the warning, or must it be in person?

Deliver in person or via video when possible, then provide a written copy by email or HRIS for records. Confirm receipt and store documentation in the employee file.

How do I track progress during the improvement period?

Use your timekeeping system to review weekly attendance and schedule brief check ins. Summarize each check in with a short note and share it with the employee.

What if the employee disputes the dates or points?

Review timekeeping records, manager notes, and any documentation the employee provides. Correct genuine errors quickly and reissue the letter if needed with an Updated notation.

When do I move to the next disciplinary step?

Escalate if the employee fails to meet expectations during the improvement period or if a serious event occurs, such as repeated no call no show. Follow your policy or CBA timeline and document each step.
