Substitution Management

Cover every class — without the group chat.

A real substitution board for fitness studios. Instructors post requests, staff claim shifts, managers approve, and registered students get the update — all in one place, with reminders, comments, and a record of what happened.

  • Centralized board — every request, one place
  • Auto-approve or queue for manager review
  • Auto-notify registered students with a note
One central board

Replace the group chat with a real workflow

Every sub request lives on one board, sorted by urgency. Open requests at the top, covered ones below, full history one click away. Staff see what's available, managers see what needs review, and nothing falls through the cracks.

  • Urgent at the top — anything within 3 days of class.
  • Filter by location, instructor, day, or class type.
  • Full audit trail on every request — who, when, why.

From request to coverage

A predictable path, every time

The board enforces the workflow your studio runs on. Instructors post, staff claim, managers approve, students get notified. Every step is logged, so when something goes wrong you can see exactly where — and when it works (which is most of the time), nobody has to think about it.

  • Direct Claim for trusted teams — instant lock-in.
  • Offer to Claim for manager-reviewed coverage.
  • Auto-approval rules per role, per location, per class type.

Pick the best fit when multiple staff offer

When two or three instructors offer to cover the same shift, the board surfaces every offer side-by-side — with their notes, sub history, and on-time stats. You pick the best fit, optionally add a note, and the others get a polite "covered by someone else" notification.

  • Side-by-side offers with sub track record.
  • Approval notes that go back to the staff member.
  • Withdraw before approval — clean cancellations.

Student notifications

Tell registered students before they show up

The moment a sub is approved, the registered students can be notified by email and push — with a custom note from the manager or the original instructor. No more "wait, where's Mara?" at 6:00 AM. Members come in expecting the right person.

  • Optional notification — turn it off for last-minute changes.
  • Custom note goes out with the email and push.
  • Booking app updates with the new instructor in real time.

Automatic reminders

Urgent reminders for unclaimed shifts

When a sub request is still open within 3 days of the class, Zipper automatically nudges every eligible staff member by email and push. You don't have to play air-traffic-controller in a group chat — the system pings who needs to know, when they need to know.

  • Auto-reminders within the urgency window.
  • Notifications for every event — claim, offer, approve, decline.
  • Push + email + in-app — staff pick the channels.

Coordinate logistics on the request itself

Every sub request has a comment thread — equipment notes, member modifications, parking instructions for subs new to the location. The conversation lives with the request, not in some Slack channel that nobody will dig through later.

  • Threaded comments tied to each request.
  • Visible to all participants — requester, sub, manager.
  • Permanent record — searchable and exportable.

Sub history & analytics

See who steps up and which classes need help

The board tracks every request, every claim, every approval — so you can see who's been a hero and who's consistently posting last-minute, which classes drain coverage, and which locations are most stable. Use it for end-of-quarter reviews, performance bonuses, or just to send a thank-you note.

  • Sub leaderboard — most active staff, top reliability.
  • Class-level coverage — see which slots burn through subs.
  • Exportable history for HR or operations review.

Notifications that work
Email, push, and in-app — every event in the lifecycle gets the right people without spam.
One platform, one bill
Subs, scheduling, payments, marketing — all under a single subscription, no duct tape.

Common questions

What is the Substitution Board?
A built-in tool for managing class coverage when an instructor can't teach a session. Instructors post sub requests, staff offer to cover, managers approve, and the registered students get notified — all in one place with a full audit trail.
Why use this instead of a group chat?
Group chats are easy to miss, hard to track, and leave no record of what happened. The board surfaces high-priority requests, sends automatic reminders for unclaimed shifts, tracks who subs the most, and keeps the conversation tied to the actual class on your calendar.
How does an instructor post a sub request?
Click Post Sub Request, pick the class from your schedule (or enter the details manually), add notes — equipment setup, what to focus on, anything the sub needs to know — and post. The request becomes visible to all eligible staff immediately.
Can I link a sub request to the actual class on my calendar?
Yes. When the sub request is linked to a calendar event, the system automatically updates the instructor on that event the moment a sub is approved — so the schedule, the booking app, and reminder emails all reflect the new instructor in real time.
How do staff claim a shift?
Two ways depending on how you set things up. Direct Claim — the staff member taps Claim and the sub is locked in immediately. Or Offer to Claim — the staff member submits an offer, and a manager reviews and approves the best fit. You pick which mode fits your studio.
Can multiple people offer to cover the same shift?
Yes. With Offer to Claim turned on, multiple staff can submit an offer on the same request. The manager sees every offer and picks the best one, with optional notes to other applicants.
What happens if a sub falls through?
The original requester, the person who claimed the shift, or an admin can unclaim it — and the request goes back to "available" so other staff can pick it up. Withdrawals before approval are also supported.
Can I notify the registered students about the instructor change?
Yes. When the manager approves a sub, they can choose to notify everyone registered for that class with a custom note ("Theo will be subbing for Mara today — see you all there!"). The note lands in email and push notifications instantly.
What notifications get sent automatically?
Every key event triggers a notification: new sub request posted, shift claimed, offer submitted, claim approved or declined, comment added, shift unclaimed. And if a request is still open within 3 days of the class, urgent reminders go out to all eligible staff.
Do you track who subs the most?
Yes. The board tracks every sub request, claim, and approval — so you can see who steps up most often, which classes need the most coverage, and how reliable each staff member is when it counts.
