A labor-law problem can first be seen at one of three points: the schedule, the clock-in or the timecard. Catch it on the schedule and you can still prevent it. Catch it at the clock-in or on the timecard and you can at least pay it right, on time. Payroll is the one place where it's already too late, so the goal is to know, rule by rule, where each one first shows up.
Picture a distribution centre in Ontario. A picker who normally works eight-hour shifts is called in on a Saturday. Two hours later the work dries up and she's sent home, even though she could have stayed.
Ontario's Employment Standards Act says she gets paid for at least three hours at her regular rate anyway[1]. Not two. Three.
Sending her home wasn't against the law. The law just put a price on it. And that price is easy to miss, because nobody decided to pay a third hour. It only shows up when someone compares her clock-out to the rule.
That's what this guide is about. Some labor-law problems you can prevent. Others you can only pay for. Below is the idea in one minute, then how it works country by country: Canada, the United States, the United Kingdom, Ireland and Australia.
The idea in one minute
Every rule you follow first becomes visible at one of three points in the week. The earlier the point, the more options you have.
-
1
The schedule, before it goes out Prevent
Rules you can know in advance: rest between shifts, how much notice people get, how much overtime the week is heading for. Caught here, a problem can still be avoided.
-
2
The clock-in and clock-out Detect
What only the real shift shows: someone stayed late, clocked in at another site, or was sent home early.
-
3
The timecard, before it goes to payroll Classify
Every hour gets its label: regular, overtime, premium. Caught here, at least it gets paid right and on time.
-
4
Payroll Correct
Nothing new can be caught here, only fixed after the fact: back pay, a late premium, a grievance.
If your team first sees a broken rule at payroll, the fix starts with the schedule.
How it works in Canada
Each province and territory sets its own hours rules[2]. Federally regulated industries, such as airlines and airports, banks, telecommunications, ports and marine shipping, and trucking and rail that cross borders, follow the Canada Labour Code instead[3].
On the schedule. Under the federal Code, workers generally get their schedule in writing at least 96 hours before their first shift. They can refuse a shift that starts inside that window, except in an emergency the employer could not have foreseen[4]. You either meet that rule in the draft schedule, or you don't meet it at all.
At the clock-in. In British Columbia, a worker gets time and a half after 8 hours in a day and double time after 12[5]. Say a 12-hour shift runs 30 minutes long because the relief is late. That half hour is double time, and only the clock-out shows it.
On the timecard. Ontario's three-hour rule from the opening lands here. So does Alberta's overtime, which is generally whichever is bigger: the hours over 8 each day, or the hours over 44 that week[6]. Four 10-hour days plus one 4-hour day add up to 44 hours, so there's no weekly overtime. But each long day has 2 hours over 8, so the person is owed 8 hours of overtime. A weekly total can't show you that.
When a union agreement applies. In British Columbia, if a collective agreement's terms on hours and overtime, taken together, meet or beat the law, the agreement replaces that part of the law[5]. So two people on the same shift, one covered by such an agreement and one not, can be owed different pay for the same extra half hour.
Watch for:
- Ontario's three-hour rule covers people who usually work more than 3 hours a day and were available to stay. It doesn't apply when fire, a power failure, a storm or a similar cause beyond the employer's control stops the work, and some groups are exempt[1][7].
- The federal 96 hours can be changed or switched off by a collective agreement. Managers are excluded, and so are some occupations, including some truck drivers and longshore workers[4][8].
- In British Columbia, averaging agreements change the daily count, and managers, teachers and some others are outside the overtime rules, while some jobs, truck drivers among them, have their own overtime thresholds[5][9].
- In Alberta, averaging arrangements and overtime agreements change the math, some industries use other thresholds, and supervisors and managers, among others, are excluded[10].
How it works in the United States
Chicago and California show the pattern well.
On the schedule. Chicago doesn't forbid late schedule changes. It charges for them. Add hours to a covered employee's shift, or move it, within 14 days of the schedule starting, and you generally owe them one extra hour of pay[11].
At the clock-in. California works like British Columbia by default: time and a half after 8 hours in a day, double time after 12[12]. The same late relief creates the same half hour of double time.
On the timecard. In Chicago, a covered employee who works a shift starting less than 10 hours after the end of the previous day's shift is paid at least 1.25 times their regular rate for it[11]. That premium, and the one for late changes, must be paid by the next payday and listed separately on the pay stub or another written record[13].
When a union agreement applies. California's overtime rules don't apply to employees under a qualifying collective agreement, one that sets their pay and hours, pays a premium for all overtime and pays at least 30 percent above the state minimum wage[12]. Chicago's rules can be waived by a union agreement, but only if it says so explicitly[14].
Watch for:
- Chicago's rules apply only to covered employees, the city lists exceptions for late changes, and split shifts follow their own rest rule. Union agreements already in force on July 1, 2020 keep their terms[11][13][14].
- California's daily overtime has its own exceptions, including exempt staff and alternative workweek schedules, and a seventh day in a row in the same workweek has its own rates[12].
How it works in the United Kingdom
On the schedule. In Great Britain, an adult worker gets at least 11 hours of rest in a row between working days, and a worker under 18 gets 12[15]. That's a rule you meet in the draft.
On the timecard. There's no legal overtime rate. Employers don't have to pay extra for overtime, as long as average pay stays at or above the National Minimum Wage. If the employment contract sets an overtime rate, and it usually says so when it does, those hours need their own label so the rate gets paid[16].
Watch for: the adult 11 hours has several exceptions, among them shift changeovers, work split up over the day, emergencies, some sectors, and roles where working time isn't measured, such as managing executives. A collective or workforce agreement can also change the adult rule, with equivalent rest wherever possible. The under-18 rest can be interrupted for split or short-duration work[15].
How it works in Ireland
On the timecard. An employee required to work on a Sunday must be compensated for it: with an allowance, higher pay, paid time off, or a mix[17]. The Sunday hours have to be picked out on the timecard before anyone can apply that.
Watch for: it isn't owed again if Sunday work is already built into the person's pay, and some groups are excluded[17].
How it works in Australia
On the timecard. Under the General Retail Industry Award, an employee who comes back to work without a 12-hour break is paid 200% of their minimum hourly rate until they get one[18]. The short turnaround already happened. The only question left is whether those hours are paid at the right rate.
Watch for: this rule comes from that award, and the employer and employee can agree to a 10-hour break instead[18].
How WorkAxle handles it
On the schedule. As someone builds or edits a schedule in WorkAxle, every change is checked against your rules, and a conflict shows up as a warning before anything is published. On a late change in a city like Chicago, the person making it sees that it carries a premium. They can still go ahead, and the system logs who did it, when and why. That log matters: sometimes paying the premium is the right call, and the expensive version is paying it without knowing.
At the clock-in. Each clock-in is checked for identity and location, and a punch at the wrong site or off the schedule is flagged the moment it happens.
On the timecard. Overtime, premiums and differentials are labeled by the rule engine as the hours come in. A manager approves the timecard, and payroll gets hours that are already sorted instead of rebuilding them by hand.
Across places and agreements. Each person's hours run against the rules for their location and their agreement, side by side in one system. A complex agreement is written into rules once, by your labor-relations team and a WorkAxle engineer together. After that, your team keeps the rules up to date without code. Rules carry the date they took effect, so you can show how a rule stood on any past day.
None of this writes the rules for you. Someone still has to read each law and each agreement and get them right. What changes is that each rule lives in one place, instead of in a scheduler's head and a payroll spreadsheet.
Check your own process in fifteen minutes
You don't need new software to find your gaps. You need a short list.
- Write down the five rules that cost you money, a grievance or an audit finding last year.
- Next to each, write where it could first have been seen: the schedule, the clock-in or the timecard.
- Then write where your team actually finds it today.
Every rule where those two answers don't match is a gap. Every rule you first find at payroll, or in a grievance, is the expensive kind. Bring that list to any vendor demo, ours included, and ask to see each rule caught at its earliest point, using your rules rather than a sample.
Bring the rule that keeps showing up at payroll. We'll show you where it surfaces first.
