Suggestion
No specific policy or standard cited. Warnings that cite a written policy or expectation hold up far better in disputes than vague references to "professionalism" or "attitude".
About this template
Progressive discipline — verbal, written, then final written warning before termination — is the documented chain that turns a problem conversation into a defensible employment decision. A well-drafted warning letter is specific, fair, and gives the employee a real chance to correct course.
When to use it
- An employee has breached a policy or standard and informal coaching hasn't worked.
- You're escalating from a verbal warning to a written one, or to a final written warning.
- You want a documented record before considering for-cause termination.
What to include
- Warning level — verbal (documented), written, or final written.
- A specific, factual description of the conduct.
- The policy, standard, or expectation that was breached, quoted where possible.
- Reference to any prior warnings on related conduct.
- Required corrective action with concrete behaviours and dates.
- An honest consequence statement.
- Space for the employee to respond in writing.
Frequently asked questions
Do I need to issue a verbal warning before a written one?
For most performance and conduct issues — yes, ideally. Some misconduct (theft, violence, harassment) is so serious that you go straight to termination. Most everyday issues should follow the verbal → written → final written → termination ladder, with appropriate gaps between rungs and clear opportunities to correct.
What if the employee refuses to sign?
Same as a PIP — the signature is acknowledgement, not agreement. Note the refusal in writing, have a witness sign that the warning was delivered and explained, and place both in the file. Don't let a refusal to sign delay or weaken the documentation.
Can I skip warnings if the misconduct is serious enough?
Yes, for genuinely serious misconduct. Theft, intentional violation of safety rules, harassment, or violence rarely require a graduated-discipline trail. Performance issues, attendance problems, and minor conduct issues almost always do.
Legal disclaimer. Progressive discipline matters most in for-cause termination disputes. A documented chain of warnings on the same conduct, paired with genuine opportunity to correct, is often the difference between a defensible just-cause termination and a wrongful-dismissal payout. In Quebec, the same chain supports the "motif sérieux" standard. Generic, undated, or boilerplate warnings frequently undermine rather than support an employer's case.
