Can You Call In Sick During Your Probation Period?
You can report an illness during probation. Whether an absence is job-protected, what notice is required, and whether documentation is relevant depends on your province, workplace policy, collective agreement, and contract. A medical note can document a clinically appropriate short-term illness, but it does not guarantee that an employer will make a particular employment decision.
Your Legal Rights During Probation
Employment Standards Still Apply
Probation does not remove all legal protections, but provincial rules are not identical. For example, Ontario's ESA sick leave, BC's illness or injury leave, and Alberta's personal and family responsibility leave each have their own eligibility and documentation context. Check the current provincial source and your workplace materials before relying on a general rule.
Human Rights Protection
If your illness is related to a disability (including mental health conditions), human rights legislation protects you from discrimination regardless of your employment stage. Your employer has a duty to accommodate even during probation.
What Probation Actually Means Legally
Probation periods (typically 3-6 months) allow employers to terminate employment with less notice. However, they do not:
- Remove your right to sick leave
- Allow termination for discriminatory reasons (including disability)
- Override employment standards legislation
- Permit retaliation for legitimate medical absences
The Real Risk: What Employers Can Do
Here is the honest truth about probation:
During probation, employers can terminate you with minimal notice (often 1-2 weeks or none, depending on your contract). They do not need to provide a reason in most provinces. This means:
- They cannot fire you "because you were sick" (that is discrimination)
- They can fire you during probation for "not being the right fit" without elaborating
- Proving the real reason was your illness is difficult (but not impossible)
This is why many employees are anxious about being sick during probation - not because it is illegal to fire them, but because the burden of proof is harder.
How to Protect Yourself
1. Follow the Reporting Process and Keep Records
Notify the employer through the required channel as soon as reasonably possible and keep a copy of the message. If medical documentation is requested or you decide it is appropriate for a short-term illness, it may help explain the absence; it is not a substitute for employment-law advice and does not determine the outcome of a complaint.
2. Follow Proper Procedures
- Notify your employer as early as possible (before your shift starts)
- Follow the exact notification procedure in your employee handbook
- Keep records of all communications (texts, emails)
- Provide a sick note if requested (or proactively)
3. Communicate Professionally
"I am unwell today and unable to come in. I have a doctor's appointment and will provide documentation. I expect to return [date]. I apologize for any inconvenience."
4. Do Not Over-Explain
You do not need to describe your symptoms in detail. "I am unwell and have medical documentation" is sufficient.
5. Document Everything
If you are terminated shortly after a sick absence during probation, document:
- The dates of your illness and notification
- Your medical documentation
- The date and reason given for termination
- Any comments made about your absence
When to Be Extra Careful
Certain situations during probation warrant extra caution:
| Situation | Risk Level | Recommendation |
|-----------|-----------|----------------|
| Single day absence with note | Low | Follow normal procedure |
| 2-3 day absence early in probation | Medium | Provide note proactively, communicate clearly |
| Week+ absence in first month | Higher | Get detailed documentation, consider discussing with HR |
| Pattern of Monday/Friday absences | High | Get notes for each absence, be transparent |
| Chronic condition requiring ongoing absences | Medium | Consider disclosing to HR for accommodation |
Should You Disclose a Chronic Condition During Probation?
This is a personal decision with no single right answer:
Arguments for disclosing:
- Triggers duty to accommodate
- Creates legal protection if terminated
- Allows employer to plan around your needs
- Demonstrates honesty and professionalism
Arguments against disclosing:
- Potential unconscious bias in evaluation
- May affect perception of your capabilities
- Difficult to prove discrimination if terminated
- Not legally required unless requesting accommodation
Our recommendation: If your condition will require regular absences or accommodations, disclose early and in writing. If it is a one-time illness, treat it like any other sick day.
What If You Are Fired During Probation After Being Sick?
If you believe you were terminated because of illness:
1. Request the reason in writing - Employers often avoid putting discriminatory reasons on paper
2. Consult an employment lawyer - Many offer free 30-minute consultations
3. File a human rights complaint - If the illness is disability-related
4. Contact employment standards - If your statutory rights were violated
5. Keep all documentation - Sick notes, communications, performance reviews
Frequently Asked Questions
Can I be fired for calling in sick once during probation?
Legally, no - you cannot be fired specifically for a legitimate illness. Practically, employers during probation can terminate without cause with minimal notice. However, if the timing suggests the illness was the reason, you may have grounds for a complaint.
Should I go to work sick during probation?
No. Going to work sick can spread illness to colleagues, reduce your performance (making a worse impression), and delay your recovery. A single well-documented sick day is far better than a week of poor performance while ill.
How many sick days can I take during probation?
There is no single Canada-wide number. Leave eligibility can depend on the province, length of employment, the type of leave, and the workplace arrangement. Review the applicable employment-standards source and your contract or collective agreement.
Do I need a sick note for 1 day during probation?
Check your employer's policy. Many employers do not require notes for single-day absences. However, during probation, proactively providing a note demonstrates professionalism and creates documentation.
What if I have a pre-existing condition - should I mention it in the interview?
You are not legally required to disclose medical conditions during hiring unless they directly prevent you from performing essential job duties. However, if you will need regular accommodations, early disclosure is often strategic.

Need short-term illness documentation during probation? MedLetter accepts online requests for one-to-five-day acute illnesses such as cold, flu, food poisoning, or a stomach bug. A licensed physician independently decides whether documentation is clinically appropriate; review timing and any employer decision can vary.
