Part-Time Workers & Sick Notes in Ontario: Your Rights
If you work part-time in Ontario, you have the same fundamental sick leave rights as full-time employees under the Employment Standards Act (ESA). Many part-time workers do not know this, and some employers take advantage of that knowledge gap. With over 1.5 million Ontarians working part-time, understanding your rights is essential.
Your ESA Rights as a Part-Time Worker
The ESA does not distinguish between full-time and part-time employees for sick leave purposes. If you have worked for your employer for at least 2 consecutive weeks, you are covered:
| Right | Full-Time | Part-Time | Casual/On-Call |
|---|---|---|---|
| 3 unpaid sick days per year | Yes | Yes | Yes (if 2+ weeks) |
| No sick note for first 3 days | Yes | Yes | Yes |
| Job protection during sick leave | Yes | Yes | Yes |
| Cannot be fired for legitimate illness | Yes | Yes | Yes |
| Human Rights Code protections | Yes | Yes | Yes |
| Employer cannot reduce hours as retaliation | Yes | Yes | Yes |
Common Myths About Part-Time Sick Leave
Myth 1: "Part-time workers do not get sick days"
False. All employees covered by the ESA get 3 unpaid sick days per calendar year, regardless of hours worked. Whether you work 4 hours a week or 30, you are entitled to the same protections.
Myth 2: "Employers can require a note for any absence"
The ESA prohibits employers from requiring a sick note for your first 3 sick days. However, many employers still request documentation beyond those 3 days, and having a note protects you from disciplinary action. A $49 same-day note from MedLetter is insurance against job loss.
Myth 3: "Part-time workers can be replaced if they call in sick"
False. Your employer cannot permanently replace you or reduce your hours as retaliation for legitimate sick leave. If your hours suddenly drop after a sick day, document it, this may be illegal reprisal.
Myth 4: "Probationary part-time workers have no protections"
False. ESA sick leave protections apply from day one of employment (after the 2-week qualifying period). Probation does not eliminate your statutory rights.
Myth 5: "If I am scheduled for a shift and call in sick, I lose the shift permanently"
Your employer must offer you equivalent future shifts. Permanently removing you from the schedule after a legitimate sick absence is constructive dismissal.
When Part-Time Workers DO Need a Sick Note
You may need documentation if:
- Your absence exceeds 3 consecutive scheduled shifts
- Your employer's written policy (established before your absence) requires it for longer absences
- You are applying for EI Sickness Benefits
- You need workplace accommodations for an ongoing condition
- You are requesting a leave of absence beyond your 3 ESA days
- You want to protect yourself from an employer who has a history of retaliating against sick workers
Industries Where Part-Time Workers Face the Most Pressure
| Industry | Common Issue | Your Right |
|---|---|---|
| Retail (Walmart, Loblaws, Shoppers) | Threatened with shift reduction | Cannot reduce hours as retaliation |
| Food service (Tim Hortons, McDonald's) | Told to find own replacement | Not your responsibility under ESA |
| Warehousing (Amazon, Purolator) | Attendance point systems | Points cannot override ESA rights |
| Healthcare (PSW, home care) | Pressured to work while sick | Patient safety supports your absence |
| Gig economy (Uber, DoorDash) | Classified as "contractor" | May still be an employee under ESA |
| Hospitality (hotels, restaurants) | Told "no show = fired" | Illegal if absence is legitimate illness |
Real Scenarios: What the Law Says
Scenario 1: You work 15 hours/week at a retail store. You call in sick on Saturday (your busiest shift). Your manager texts: "If you can not come in, do not bother coming back." This is illegal termination. You are protected.
Scenario 2: You work part-time at a restaurant. After calling in sick twice in one month, your hours are cut from 20 to 8 per week. This is likely illegal reprisal. Document the schedule change and file a complaint.
Scenario 3: You are a part-time PSW. Your agency says you need a doctor's note for any absence, even one shift. For your first 3 sick days per year, they cannot legally require this. However, having a note protects you from disputes.
What to Do If Your Employer Violates Your Rights
1. Document everything, Save texts, emails, schedules, and any communication showing retaliation or threats
2. File a complaint with the Ministry of Labour, Ontario's Employment Standards branch investigates violations. Complaints can be filed online.
3. Contact the Human Rights Tribunal, If you believe discrimination is involved (disability, race, pregnancy)
4. Get legal advice, Many employment lawyers offer free 30-minute consultations. Community legal clinics provide free help for low-income workers.
5. Know the timeline, You have 2 years to file an ESA complaint from the date of the violation

Frequently Asked Questions
Do part-time workers qualify for EI Sickness Benefits?
Yes, if you have accumulated enough insurable hours (420-700 depending on your region's unemployment rate). Part-time hours count toward this threshold.
Can my employer require a sick note for one missed shift?
For your first 3 sick days per calendar year, no, the ESA prohibits this. Beyond 3 days, employer policy may require documentation.
What if I work multiple part-time jobs?
Each employer relationship is separate. You get 3 ESA sick days per employer per year. However, EI Sickness Benefits consider your total insurable earnings across all jobs.
Can my employer fire me during my probation for calling in sick?
They cannot fire you specifically for taking legitimate sick leave, even during probation. However, proving the reason was your sick day (vs. other performance issues) can be challenging, documentation helps.
