A schedule is a promise. When it’s posted late, changed every other day or lives in a blurry photo in a group chat, people stop trusting it, and that’s when the no-shows, the swaps nobody approved and the “I didn’t know I was on” start. The good news is that a reliable schedule isn’t complicated. It just needs to be built in the right order.
Step 1: start from demand, not from people
The most common mistake is starting with who’s available. Start instead with how many people you need, hour by hour:
- Your opening hours, plus time to open and close.
- The busy periods: lunch, evenings, weekends, delivery days.
- The minimum per shift for safety or service (no one alone at closing, at least one key holder, at least one person trained on the till).
Write it as a simple grid: days across the top, hours down the side, the number of people needed in each cell. That grid is your schedule’s skeleton. Everything else is filling it in.
Step 2: list the fixed constraints
- Contracted hours for each person, and any maximum.
- Availability: childcare, studies, a second job. Ask once, in writing, and ask people to tell you when it changes.
- Skills: who can open, who can cook, who can drive.
- Time off already approved. Put it on the schedule before anything else, so nobody gets rostered on a day they booked off months ago.
- Legal limits, which come in step 4.
Step 3: choose a pattern
There are two broad approaches, and most small businesses end up mixing them:
- Fixed shifts. The same people on the same days and times every week. Easy to plan around, and people like the predictability. It works when demand is stable.
- Rotating shifts. People move through early, late and weekend shifts in a cycle. Fairer when some shifts are less popular, but harder to plan your life around, so publish it further in advance.
Split shifts (say 10:00 to 14:00 and 18:00 to 22:00) are common in hospitality. If you use them, make sure your system adds up both blocks correctly and that the gap between them really is free time.
Step 4: check rest and notice rules
This is where countries differ most. A selection of the rules that most often affect a weekly schedule:
| Where | Rest | Notice of hours |
|---|---|---|
| Great Britain | 11 hours between working days; a 20-minute break if the day is over 6 hours; 24 hours off a week (or 48 a fortnight) | No general legal notice period; check contracts |
| Ireland | 11 hours daily rest; 15 minutes after 4½ hours, 30 minutes after 6; 24 hours weekly rest | At least 24 hours when the contract doesn’t set the start and finish times (s. 17) |
| Canada (federal) | 8 hours between shifts; 30 minutes unpaid for every 5 consecutive hours | Schedule in writing 96 hours ahead; 24 hours’ written notice of changes |
| Oregon | 10 hours between shifts, or extra pay for the hours worked inside that gap | 14 days, for retail, hospitality and food service employers with 500 or more employees worldwide |
| Australia | Set mainly by the modern award or agreement that covers the employee, including how much notice a roster change needs | |
US federal law sets no rest or notice rules for adults. Besides Oregon, “fair workweek” or predictive scheduling ordinances exist in cities including San Francisco, Seattle, New York City, Chicago, Philadelphia, Los Angeles, Evanston, Berkeley and Emeryville, each with its own scope. Canadian provinces have their own rules.
The rule that trips up most schedules is rest between shifts. Closing at 23:00 and opening at 7:00 the next morning (a “clopening”) leaves 8 hours. That breaks the 11-hour rule in Great Britain and Ireland and Oregon’s 10-hour rule.
Step 5: publish it properly
- One place, always the same. Not a photo in a group chat, not three versions in three folders.
- As early as you realistically can. Where the law doesn’t set a notice period, a week ahead is a decent minimum and two weeks is better.
- Swaps with approval. Let people swap, but through you, so the schedule shows who is really working.
- Changes in writing. If you change a shift, the change should be visible to the person affected, with the date you made it.
The mistakes behind most no-shows
- Publishing late. If the schedule arrives on Sunday night for Monday morning, you’ll get gaps.
- Always giving the worst shifts to the same people. Rotate weekends and closings, and keep a simple count so you can show it’s fair.
- Ignoring rest between shifts because “they said they didn’t mind”.
- Not checking the schedule against clock-ins. A schedule nobody compares with reality slowly drifts away from it, and overtime appears where nobody planned it.

In CheckInGO you plan each employee’s week, export it as a PDF and everyone sees their shifts on their own phone. Split shifts and night shifts add up correctly, and you can compare the schedule with real clock-ins every day. $19 a month for up to 10 employees and $2 for each extra one, plus any tax that applies. No contract, and 7 days free to try it with your team.

How far in advance should I publish a shift schedule?
Where the law sets a notice period, follow it: 96 hours in Canada’s federal sector, 14 days under Oregon’s law for large retail, hospitality and food service employers, 24 hours in Ireland when the contract doesn’t fix the hours. Elsewhere, one to two weeks ahead is good practice.
What is a clopening shift?
Closing late and opening early the next morning, such as finishing at 23:00 and starting at 7:00. It leaves 8 hours of rest, which breaks the 11-hour daily rest rule in Great Britain and Ireland and Oregon’s 10-hour rule.
Are fixed or rotating shifts better?
Fixed shifts are easier for employees to plan around and work when demand is steady. Rotating shifts share out unpopular shifts more fairly. Many small businesses use a fixed core with a rotation for weekends and closings.
Should I let employees swap shifts?
Yes, but with approval, so the schedule always shows who is actually working and you can check that the swap doesn’t break rest rules or create overtime.
Do I need to keep old schedules?
Some predictive scheduling laws and Canada’s federal rules require records of schedules and changes. Even where they don’t, keeping them alongside your time records helps if hours or pay are ever disputed.
