Shift and Evening Premiums: What Your Collective Agreement Must Cover (and What the Labour Standards Act Does Not Guarantee)

You work evenings, nights, or weekends and you're wondering whether your employer is required to pay you extra for those hours. You're not alone in asking — and the answer surprises a lot of unionized workers.

The truth is that Quebec's Act Respecting Labour Standards (ARLS, commonly known as the LNT) provides for no mandatory premium for evening, night, or weekend work. Not an extra dollar per hour, not a percentage. If you receive a premium for those shifts, it's because your collective agreement — the contract negotiated between your union and your employer — says so. If your collective agreement is silent on the matter, you have no automatic legal entitlement to any such supplement.

What the Labour Standards Act Covers (and Doesn't)

The Act Respecting Labour Standards establishes a floor: a minimum wage, annual leave, statutory holidays, notice of termination, and so on. These rights apply to all Quebec employees, unionized or not.

But the ARLS does not provide for:

• An evening or night premium
• A weekend premium
• A pay supplement for rotating shifts
• Any additional pay for working on statutory holidays beyond the entitlement to a day off or replacement day under section 62

Note: Section 55 of the ARLS guarantees the minimum wage for every hour worked, and section 67 provides for a 50% premium on overtime hours. But these provisions do not create a premium based on when during the day you work — only on how many hours you work.

Most unionized workers in Quebec are covered by both the ARLS and their collective agreement. The collective agreement can — and often must — go further than the ARLS. Shift premiums are one of the clearest examples where the collective agreement is the only source of protection.

The Four Most Common Types of Premiums

Quebec collective agreements generally provide for one or more of the following premiums. Here's how each one works in practice.

The Evening Premium

This is the most widespread. It applies to hours worked during the evening shift, with the exact time window varying by agreement — often between 4:00 p.m. and midnight, or 6:00 p.m. and midnight.

How it's calculated: It usually takes the form of a fixed amount per hour worked during the evening shift (for example, $1.25 or $1.50 per hour on top of the regular rate), or sometimes a percentage of the regular hourly rate (e.g., a 5% increase).

Concrete example: Imagine your collective agreement states: "Any employee who works the majority of their hours between 4:00 p.m. and midnight receives an evening premium of $1.50 per hour." If your regular rate is $24.00 per hour, you earn $25.50 for every hour of that shift.

The Night Premium

This applies to hours worked late at night and early in the morning — often from midnight to 8:00 a.m., but the definition varies. The night premium is generally higher than the evening premium because the constraints are more significant (sleep disruption, social life, health impacts, etc.).

What to check: Some collective agreements have separate premiums for evenings and nights; others have a single "off-day" premium that applies to both shifts.

The Weekend Premium

Some collective agreements provide a separate premium for hours worked on Saturday and/or Sunday, regardless of the time of day. This premium can be added on top of the evening premium if you work on a Saturday night — but only if your collective agreement explicitly allows stacking.

The Rotation Premium (Rotating Shifts)

In some workplaces — factories, hospitals, emergency services — workers rotate between day, evening, and night shifts on a cycle. The collective agreement may provide a rotation premium that recognizes the difficulty of that kind of schedule, regardless of which specific shift is being worked.

This premium is often negotiated as a flat amount per week or per cycle, rather than a per-hour amount.

How to Read Your Collective Agreement to Find These Premiums

Most unionized workers only read their collective agreement when something goes wrong. But a few minutes of focused reading is all it takes to know where you stand.

Practical steps:

1. Find the chapter on compensation or wages. It's often titled "Wages," "Remuneration," or "Monetary Conditions."
2. Search for the words "premium," "supplement," "differential," or "shift allowance." These keywords lead to the relevant clauses.
3. Check the definitions of each shift. Your collective agreement must specify what it means by "evening shift," "night shift," etc. The exact time windows are crucial.
4. Check the eligibility conditions. Some premiums only apply to full-time employees, or only after a probationary period (the trial period at the beginning of employment, typically ranging from a few weeks to a few months), or only for complete shifts.
5. Check whether premiums stack. Does the collective agreement explicitly say that premiums can be combined? Or does it say that only the highest premium applies?

Practical tip: If your collective agreement is available in digital format, use the "Find" function (Ctrl+F) with the keywords above. You'll locate all the relevant clauses in under a minute.

Common Traps: When the Premium Doesn't Apply the Way You Think

The "Majority of Hours" Trap

Some collective agreements define an "evening shift" not by the start time, but by the condition that the majority of hours fall within the relevant time window. Result: a worker who starts at 3:30 p.m. and finishes at 11:30 p.m. might not be entitled to the evening premium if the definition used is "a shift where the majority of hours fall between 6:00 p.m. and midnight."

The Overtime Trap

When you work overtime hours (hours beyond your normal scheduled hours, at the 150% rate under section 67 of the ARLS or a higher rate in your collective agreement), is the shift premium included in the base rate for calculating overtime? Or is it excluded? The answer depends entirely on the wording of your collective agreement.

Example: If your regular rate is $24.00 per hour and your evening premium is $1.50, your evening rate is $25.50. If you work overtime that evening, is your overtime rate $25.50 × 1.5 = $38.25, or $24.00 × 1.5 + $1.50 = $37.50? The difference seems small, but it adds up over time.

The Probationary Period Trap

Some collective agreements exclude workers who are in their probationary period (the trial period at the start of employment) from certain premiums. If you're new to your job, check whether this exclusion applies to you.

The Part-Time Trap

Part-time workers sometimes have access to shift premiums and sometimes do not. Some collective agreements include them explicitly; others limit premiums to full-time employees.

What to Do If You Think You're Not Receiving the Premium You're Owed

If you believe your employer is not paying you a premium that your collective agreement requires, here's what to do.

Step 1: Review Your Collective Agreement and Pay Stubs

First, re-read the relevant clause in your collective agreement and compare it with your pay stubs. Make sure you understand how the premium is calculated. Sometimes the premium is folded into the displayed hourly rate and doesn't appear as a separate line item.

Step 2: Talk to Your Union Steward

Your union steward (the union's representative in your workplace) is your first point of contact. They know your employer's practices and can often resolve the situation quickly, sometimes through a simple conversation with management.

Step 3: File a Grievance

If the situation isn't resolved, your union can file a grievance — the formal procedure under the Labour Code to challenge a violation of the collective agreement. A grievance (in French, grief) is first handled through successive meetings between the union and the employer. If unresolved, it can be referred to arbitration, where an independent arbitrator will make a binding decision.

Important: Deadlines for filing a grievance are tight — often 15 to 30 days after the event being contested. Don't delay in contacting your steward.

Step 4: Document Everything

Keep your schedules, pay stubs, and any relevant communications with your employer. These documents will be essential if the grievance proceeds to arbitration.

The Special Case of Federally Regulated Workers

If you work in a federally regulated sector — banking, telecommunications, interprovincial transportation, broadcasting, certain postal services, among others — the Canada Labour Code governs your minimum standards, not Quebec's ARLS.

The situation is the same: the Canada Labour Code provides for no mandatory premium for evening, night, or weekend work. Again, everything depends on your collective agreement.

The main differences lie in certain overtime and leave rules, but for shift premiums, the principle is identical: without a clause in the collective agreement, no premium is guaranteed.

What Collective Bargaining Typically Aims to Win

Understanding your current premiums is valuable. Knowing what other unions are bargaining for is even better — especially if your collective agreement is coming up for renewal.

In many sectors, unions seek to negotiate:

• Higher premium amounts, especially in an inflationary context where fixed premiums lose real value over time
• Indexation of premiums to the cost of living or to the minimum wage
• Inclusion of premiums in the base rate for calculating overtime and statutory holiday pay
• Expanded eligibility to cover part-time workers and workers on probation
• Rotation premiums in workplaces where rotating schedules weren't previously recognized

If your collective agreement is coming up for renegotiation soon, these elements can form the basis of your bargaining demands.

Conclusion: Your Collective Agreement Is Your Only Safety Net for Shift Premiums

The Act Respecting Labour Standards is a floor, not a ceiling — and for evening, night, and weekend premiums, that floor is at zero. Everything above that floor, you owe to your union and your collective agreement.

That means two concrete things:

1. Know your collective agreement: Read the premium clauses, understand the definitions, and check your eligibility conditions.
2. Act quickly if something seems off: contact your union steward and respect the grievance deadlines.
