Seasonal Staff Certification and Skill Sync

Seasonal staff workflow that watches Google Sheets roster rows, validates required fields, separates valid and invalid entries, routes seasonal service staff through recertification timing calculation (due date one year after last certification), upserts records into Airtable Skills and Safety, sends Slack certification alerts to shop managers when certifications are missing or expired (with location-to-channel mapping), logs invalid rows to a Google Sheet for HR review, and catches failures with a Slack workflow error alert.

Seasonal Staff Certification and Skill Sync workflow

Context

A service department needed to keep seasonal staff certification and skill records synchronized, automatically calculate recertification due dates, and alert shop managers when certifications are missing or expired while maintaining accurate records in Airtable.

Approach

Built a two-part n8n workflow system with a Google Sheets roster watch trigger and a global error catch trigger. The main flow validates required fields, splits valid and invalid entries, routes seasonal service staff through recertification due date calculation (one year after last certification), upserts structured records into Airtable, checks for missing or expired certifications, maps location to Slack channel, and sends Slack cert alerts to shop managers; invalid entries are logged to an error sheet for HR review.

Architecture

Workflow 1
  1. Google Sheets: Watch Staff Roster
  2. Code: Validate Required Fields
  3. Split Out: Valid Entries / Invalid Entries
  4. Invalid: Google Sheet: Log Error Row
Valid
  1. If: Is Seasonal?
  2. Yes: If: Seasonal - Service or Sales?
  3. Service: Code: Calculate Safety Recertification Due Date
  4. Airtable: Upsert Skills & Safety Data
  5. If: Needs Cert Alert?
  6. Code: Map Location to Slack Channel
  7. Slack: Cert Alert
Sales
  1. Set: Tag Sales Staff
  2. Airtable: Upsert Skills & Safety Data
  3. If: Needs Cert Alert?
  4. Code: Map Location to Slack Channel
