Prompt Chain: Automate Shift Coverage When Employees Call Out
For QSR Assistant Managers ·
What This Builds
Instead of spending 30-60 minutes calling and texting every time an employee doesn't show up, this automation does the work for you: when a shift is marked as uncovered in your scheduling app, it automatically texts a targeted list of available employees asking them to claim it. The first person to reply YES gets it, and you're notified. You go from reactive scrambling to a 2-tap resolution.
Prerequisites
- 7shifts account (free tier or above) at app.7shifts.com
- Zapier account (free tier at zapier.com, which includes 100 tasks/month)
- A Twilio account (twilio.com, free trial includes $15 credit, about 500 SMS messages)
- About 2 hours of uninterrupted setup time (do this on a day off or slow morning)
- A list of employee phone numbers
The Concept
Think of this automation as a phone tree that works itself. Normally when someone calls out, you manually text 5-10 people one by one, waiting for replies, maybe calling some of them. This workflow does that automatically:
- You mark a shift as "open" in 7shifts
- Zapier detects the change
- Zapier sends a text message to a group of available employees via Twilio
- You get notified when someone replies YES
- You confirm the pickup in 7shifts
It's like having a coordinator whose only job is covering call-outs, except it costs about $5/month to run.
Build It Step by Step
Part 1: Set Up Your Accounts
Twilio (5 minutes):
- Go to twilio.com → click Start for free
- Create an account with your email
- When prompted for "What are you building?" select SMS / Messaging
- Twilio will provision a phone number for you (note it: this is your "from" number for texts)
- Go to Account → note your Account SID and Auth Token. You'll need these in Zapier
Zapier (5 minutes):
- Go to zapier.com → create a free account
- No setup needed yet. You'll use it in Part 2
Part 2: Create Your Zapier Automation
- Log into zapier.com → click Create Zap
Trigger: "When a shift becomes uncovered in 7shifts":
- Search for 7shifts as your trigger app
- Select trigger event: New Open Shift (or Shift Updated, whichever fires when a shift is open/uncovered)
- Connect your 7shifts account (Zapier will ask for your 7shifts API key, found in 7shifts under Settings → API)
- Test the trigger by marking a future shift as open in 7shifts, then verify Zapier detects it
Action: "Send SMS via Twilio":
- Add a Zap step: search for Twilio
- Select action: Send SMS Message
- Connect your Twilio account (use the Account SID and Auth Token from Part 1)
- Configure the message:
- From: your Twilio phone number
- To: for now, set this to your own phone number to test
- Message body:
[Store Name] — Shift available: [shift date] [shift time]. Reply YES to claim it. First YES gets it. Reply STOP to opt out.
```
- Use Zapier's data fields to pull the date and time from the 7shifts trigger data
**Test the full automation:**
- Mark a test shift as open in 7shifts
- Wait 60 seconds
- Check your phone. You should receive the text
If the text arrives: your basic automation is working.

### Part 3: Send to Multiple Employees
The free Zapier plan sends one message per trigger. To text multiple employees, use one of these approaches:
**Option A (Easiest, Free):** Create a Twilio Messaging Service
1. In Twilio, go to **Messaging** → **Services** → **Create Messaging Service**
2. Add your employees' phone numbers as recipients
3. In Zapier, change the **To** field to your Messaging Service SID
4. Twilio will send to all numbers in the service
**Option B (More Control, Paid Zapier):** Add a multi-step Zap
- On Zapier's paid plan ($20/mo), you can loop through a list of phone numbers and send individual texts
- This allows more customization (e.g., only text employees with matching availability)
For most QSR locations, **Option A is sufficient**. It's free and broadcasts to all employees.

### Part 4: Handle Replies and Assign the Shift
Twilio can receive SMS replies. To handle "YES" replies:
1. In Zapier, create a second Zap:
- **Trigger:** New Twilio Incoming Message
- **Filter:** Only continue if message body contains "YES"
- **Action:** Send yourself an SMS notification: "Reply: [employee name] said YES for [shift details]"
2. Manually confirm the pickup in 7shifts and notify the employee via the app
**What good looks like:** You get a text notification within minutes of marking a shift open. You spend 30 seconds confirming the pickup instead of 45 minutes scrambling.

## Real Example: Actual Workflow End-to-End
**Setup:** You've configured the automation with 8 available employees in the Twilio messaging service.
**Input:** At 6:45am, Jamie texts you: "Can't come in today." You open 7shifts on your phone, find Jamie's 11am-7pm shift, and mark it as "Open."
**What happens automatically:**
- Zapier detects the open shift within 60 seconds
- Twilio sends a text to all 8 employees: "[Store Name]. Shift available today 11am-7pm. Reply YES to claim it."
- Marcus replies YES at 7:02am
- You get a notification text: "Marcus replied YES for today's shift"
**Output:** You open 7shifts, assign the shift to Marcus, and confirm. Total your time: 3 minutes. Old total: 45 minutes of calls and texts.
**Time saved:** 40+ minutes per call-out, 3-5 call-outs per week = 2-3 hours of recovered management time per week.

## What to Do When It Breaks
- **Zapier says "trigger not found"** → Check that your 7shifts API key is still valid (Settings → API in 7shifts). Re-authenticate the connection in Zapier if needed.
- **Twilio texts not sending** → Check your Twilio account balance, the trial credit can run out. Add $10 to your account ($10 covers ~350 messages).
- **Employees not responding** → The automation can't force people to reply, but you can improve it by sending a follow-up text after 10 minutes of no reply. Add a second Zapier step with a delay + second message.
- **Texts going to spam** → Have employees add the Twilio number to their contacts as "[Store Name] Scheduling"
## Variations
- **Simpler version:** Skip Twilio entirely. Create a Zapier Zap that, when a shift goes open in 7shifts, sends you an automated email or Slack message with a pre-drafted group text to copy and send manually. Less elegant but no Twilio setup.
- **Extended version:** Add a Google Forms link in the text so employees can indicate which shifts they WANT in advance, then Zapier can prioritize based on expressed interest.
## What to Do Next
- **This week:** Test the automation with your own number and verify it works end-to-end before rolling out to staff
- **This month:** Analyze whether coverage time improves by tracking time from "call-out" to "shift filled" before and after
- **Advanced:** Connect the automation to your payroll system so that claimed shifts automatically populate hours tracking
