Send employee leave alerts from Google Sheets via Slack and Gmail

📊 Description

Automate employee leave tracking and communication with structured notifications and reminders 📅📣. This workflow checks a centralized Google Sheet daily to detect when leave periods start or end. When leave begins, it notifies your HR Slack channel and reminds the employee to update their availability. When leave ends, it sends a return notification and follow-up reminder. All actions are reflected back in Google Sheets to maintain a single source of truth.
Ideal for growing teams that want a simple, reliable way to manage leave visibility without manual follow-ups or status tracking.
