Pregnancy complications can force you off work before your planned maternity leave. Here's how BC law protects you and what documentation you need.
## Maternity Leave & Sick Notes in BC: When Pregnancy Gets Complicated
Most pregnant workers plan to work until close to their due date. But pregnancy complications — hyperemesis, preeclampsia, gestational diabetes, preterm labour risk — can force you off work weeks or months early. Here's what BC law provides and what documentation you need.
### BC Maternity Leave Basics
| Detail | BC Standard |
|---|---|
| Maternity leave duration | Up to 17 weeks |
| Earliest start | 13 weeks before due date |
| Latest start | Date of birth |
| Parental leave (birth parent) | Up to 61 weeks |
| Parental leave (other parent) | Up to 62 weeks |
| Job protection | Guaranteed return to same or comparable position |
| EI Maternity Benefits | 55% of earnings, 15 weeks |
### When You Need a Sick Note Before Maternity Leave
You need medical documentation if:
- **Complications require bed rest** before your planned leave start
- **Morning sickness is severe** (hyperemesis gravidarum) and prevents work
- **High-risk pregnancy** requires reduced activity
- **You need to start leave earlier than 13 weeks** before your due date
- **Workplace conditions are unsafe** for your pregnancy
- **You need modified duties** (no heavy lifting, no chemical exposure, reduced standing)
### Common Pregnancy Complications Requiring Time Off
| Condition | Typical Time Off | Documentation Needed |
|---|---|---|
| Hyperemesis gravidarum | 2-16 weeks | Sick note + accommodation letter |
| Preeclampsia | 2-8 weeks (or until delivery) | Urgent sick note |
| Gestational diabetes (severe) | Modified duties or 1-4 weeks | Accommodation letter |
| Preterm labour risk | 4-12 weeks bed rest | Extended sick note |
| Placenta previa | 4-10 weeks | Specialist letter |
| Pregnancy-related back pain | Modified duties | Accommodation letter |
| Pregnancy-related anxiety/depression | 2-8 weeks | Mental health sick note |
### Your Rights Under BC Law
**BC Employment Standards Act:**
- You cannot be fired or penalized for pregnancy-related absences
- Your employer must hold your job during maternity/parental leave
- You can use sick leave before maternity leave starts
**BC Human Rights Code:**
- Pregnancy is a protected ground
- Employers must accommodate pregnancy-related needs
- "Undue hardship" is a very high bar
- Includes fertility treatments, miscarriage, and postpartum complications
### Financial Benefits Timeline
A typical timeline for a BC worker with pregnancy complications:
1. **Weeks 1-5 (sick leave):** Use employer-provided sick days + ESA unpaid days
2. **Weeks 6-15 (EI Sickness):** 55% of earnings for up to 15 weeks (if complications prevent work before maternity leave)
3. **Week 16+ (EI Maternity):** 55% of earnings for 15 weeks
4. **After maternity (EI Parental):** 55% for up to 35 weeks (standard) or 33% for up to 61 weeks (extended)
**Important:** EI Sickness and EI Maternity are separate benefits. You can receive both if your medical condition is separate from the normal course of pregnancy.
### Getting Documentation for Pregnancy Complications
Your documentation should include:
1. Confirmation of pregnancy complication (without unnecessary detail)
2. Statement that you are unable to perform regular duties
3. Specific restrictions if modified duties are possible
4. Expected duration of absence or restrictions
5. Whether the condition is temporary or will last until delivery
