Managing paid time off (PTO) has always been one of those unavoidable workplace challenges. Every employee needs breaks, vacations, and sick days, but keeping track of who’s away, when, and why often turns into a headache. In many organizations, PTO has long been managed with messy spreadsheets, long email threads, or clunky HR portals that nobody enjoys using.
But the way we work has changed. Teams are distributed across time zones, communication happens in real time, and Slack has become the central hub where collaboration takes place. That shift has opened the door for a new, smarter approach: managing time off directly inside Slack.
This article will walk you through three different ways to track PTO in Slack, ranging from the simplest DIY option to the most advanced and automated. We’ll explore Slack’s new Workflow Builder template, the “Slack status + spreadsheet” approach, and then dive deep into why a dedicated integration like Vacation Tracker is the smartest choice for growing teams.
By the end, you’ll know not just what’s possible, but also which option makes the most sense for your organization.
Why Bring PTO Management Into Slack?
Before we dive into the “how,” it’s worth pausing to ask why PTO management belongs in Slack at all. After all, don’t spreadsheets and HR portals get the job done?
In theory, yes. But in practice, traditional tools create more problems than they solve. Imagine an employee who emails their manager to request vacation. That email sits in the inbox until the manager gets around to it. Maybe the request is approved right away, maybe it’s forgotten. If it is approved, someone then has to manually update a spreadsheet. If two people edit the spreadsheet at once, errors creep in. Nobody else knows who’s on leave unless they dig into the file, which may or may not be up to date. The result? Confusion, duplicated work, and unnecessary delays.
Now contrast that with Slack. It’s where people already spend their day: chatting with colleagues, planning projects, and checking in with managers. Bringing PTO into Slack means employees don’t need to open a new app, search through their inbox, or hope the spreadsheet is accurate. Instead, requests, approvals, and updates all live in the same place as work conversations. The result is faster, clearer, and far less stressful for everyone.
And the need is only growing. Slack now has over 42 million daily active users worldwide, with more companies shifting to digital-first collaboration every year. At the same time, a study by Pew Research Center found that 43% of U.S. employees don’t take their full PTO allowance, often because they’re unsure how much they have left or because tracking is confusing. That makes it clear: better PTO systems aren’t just a nice-to-have; they’re essential for employee well-being and organizational efficiency.
Three Ways to Track Time Off in Slack
Not all teams are the same, and neither are their needs. That’s why Slack supports multiple ways to manage time off. Here are the three most common approaches:
- Slack Workflow Builder – a simple built-in automation tool with a pre-made time off request template.
- Slack Status + Spreadsheet – a semi-manual method where employees update their Slack status and HR maintains a central spreadsheet.
- Vacation Tracker Integration – a full-featured, automated solution built specifically for managing PTO in Slack.
Let’s take a closer look at each option.
1. Slack Workflow Builder: An Easy, Built-In Starting Point
Slack’s Workflow Builder is a native tool that allows you to create simple automations. Recently, Slack even introduced a ready-made time off request template.
Here’s how it works. You set up a workflow that includes a form where employees can fill in the details of their absence. For example, they might enter the type of leave (vacation, sick day, personal day), the dates they plan to be away, and any notes they want to include. Once they submit the form, the request is automatically sent to either a specific channel or directly to their manager for review.

On paper, this is a great step forward.
- It removes the need for employees to send individual emails, and it keeps all requests in Slack, where they’re easy to find.
- Managers can see requests as they come in, respond in real time, and keep a record of approvals right in the channel.
But Workflow Builder has its limits.
- It doesn’t calculate leave balances or enforce company policies.
- It won’t prevent someone from booking time off during a blackout period, nor will it warn them if they’re out of days.
- Managers still need to track balances somewhere else, often in a spreadsheet or HR system.
- There’s no automatic calendar sync either, which means absences won’t appear in Google Calendar or Outlook unless someone adds them manually.
Mini Story – The Small Startup Trying Workflow Builder
Take the example of a five-person design agency. They set up Slack’s PTO workflow to keep requests out of email. At first, it worked fine. But within a few months, they realized they had no way of knowing who still had days left, and conflicts kept slipping through the cracks. Their HR assistant ended up managing a spreadsheet anyway, duplicating the process. It wasn’t long before they started looking for something more robust.
For very small teams with simple PTO policies, Workflow Builder might be good enough. But as soon as complexity enters the picture, multiple policies, accruals, or cross-location teams, it quickly shows its shortcomings.
2. Slack Status + Spreadsheet: The Semi-Manual Option
Another way teams manage PTO in Slack is by using Slack statuses in combination with a spreadsheet. The idea is straightforward: when an employee is on leave, they manually change their Slack status to reflect it.
For example, someone might set their status to 🌴 “On Vacation, back Monday” or 🤒 “Sick today.” This helps colleagues know who’s available and who isn’t. Meanwhile, HR or managers maintain a spreadsheet that lists all requests and approved time off, keeping track of balances along the way.

This approach has a few advantages:
- It’s cheap and easy to set up.
- Everyone already knows how to update their Slack status, and most companies already have spreadsheets in place.
But beyond that, it’s riddled with problems.
- It relies heavily on individuals remembering to update their status,and remembering to change it back once they return.
- It doesn’t prevent overlapping absences.
- Doesn’t account for accruals or TOIL
- Makes payroll reconciliation a nightmare.
- The spreadsheet becomes the single source of truth, but keeping it accurate requires constant manual effort.
Mini Story – The 12-Person Marketing Agency
One boutique marketing agency used Slack statuses plus a shared Google Sheet. It worked until two employees accidentally booked overlapping vacations during a crucial campaign. Because the spreadsheet hadn’t been updated, the manager didn’t realize half her team would be out. The result? A missed deadline, a frustrated client, and a vow to never rely on spreadsheets again.
This system can limp along in a very small, tight-knit team. But as soon as you add multiple departments, global offices, or more complex policies, it becomes clear that Slack statuses and spreadsheets aren’t enough.
3. Vacation Tracker: The Smart Slack Integration
If Workflow Builder is the entry-level option and statuses plus spreadsheets are the DIY workaround, then Vacation Tracker is the professional solution.
Vacation Tracker was designed specifically to bring PTO management into Slack, and it transforms what used to be a frustrating process into something smooth and automatic. Unlike Workflow Builder, it doesn’t just handle requests, it manages the entire lifecycle of time off, from accruals to approvals to payroll exports.
Here’s how it works in practice.
Requesting Time Off in Slack
An employee decides they want to take a vacation. Instead of emailing their manager or hunting for a form, they simply type a Slack command like /vacation
or use the lightning bolt shortcut menu. This opens a request form directly in Slack.
The form is dynamic and intelligent. It shows the employee’s remaining leave balance before they submit, so they immediately know whether they have enough days. It also highlights any potential conflicts, such as overlapping requests with teammates, minimum notice periods, or blackout dates. The employee fills in their dates, selects the type of leave, and adds a note if needed. The whole process takes less than a minute.

Approvals Without Email
The request is instantly sent to the designated approver. Instead of opening their inbox, the manager gets a Slack notification. From there, they can approve or decline with one click, all without leaving the app. If needed, they can add a comment to explain their decision.
Because Vacation Tracker is integrated with Slack, managers also see context. For example, which teammates are already scheduled to be out. This prevents situations where half the team unknowingly books vacation during the same week.
Automatic Updates Everyone Can See
Once the request is approved, Vacation Tracker takes care of all the updates. The employee’s Slack status changes automatically to show that they’re on leave, complete with dates and an appropriate emoji. A daily or weekly digest is posted in the chosen Slack channel, so everyone knows who’s away and when they’ll return.
Approved leave also syncs with external calendars like Google Calendar and Outlook, blocking off the dates so there are no surprises when scheduling meetings.

Advanced Features That Scale
Vacation Tracker goes far beyond what Workflow Builder or spreadsheets can offer. It automatically calculates accruals, whether monthly, bi-weekly, or even hourly. It supports TOIL (time off in lieu), allowing employees who work extra hours to bank that time as leave.
For global teams, it applies the correct public holidays based on employee location, ensuring balances reflect local calendars. It handles multiple policies at once, so a marketing team in New York can have one set of rules while a development team in Berlin has another.
And for HR and finance, it generates detailed reports. Managers see only their team’s data, HR sees the entire organization, and individual employees only see their own balance—thanks to role-based access controls.
Case Study — Drury Design: Event Production That Stays in Sync
The Challenge: Before Vacation Tracker, Drury Design juggled fragmented processes, manual leave requests, scattered availability updates, and frequent miscommunications.
The Breakthrough: When their IT director discovered Vacation Tracker, everything changed. He described what they were looking for in plain terms:
“We needed something that was easy to use, required little oversight, and worked with the tools we already had in place.”
With Vacation Tracker, they were able to:
- Enable quick time-off requests inside Slack. No emails, no spreadsheets.
- Make team availability visible across departments.
- Cut down on approval bottlenecks.
- Eliminate the need to log into separate systems just to check PTO balances.
The Impact: By replacing scattered leave-tracking methods with a unified, automatic Slack-based solution, Drury produced faster, more agile teams. Managers made informed plans, employees stayed accountable, and IT/HR no longer chased down time-off records. As Vladimir put it, once set up, “it just ran quietly in the background.”
Governance, Security, and Control
PTO isn’t just about time off. It’s about sensitive data, compliance, and accountability.
Vacation Tracker provides advanced governance tools:
- Approver roles: Assign managers or department heads as approvers.
- Backup approvers: Ensure requests are never delayed if someone is out.
- Role-based permissions: HR sees everything, managers see their team, employees see only their own balance.
- SOC 2 Type II compliance: Vacation Tracker meets strict security standards, so leave data is handled safely.
For HR and finance leaders, this means PTO data is accurate, secure, and ready for audits if needed.
Final Thoughts
Managing PTO should never feel like a burden. With Slack as your communication hub, you already have the perfect platform to handle it. The question is just how sophisticated you want your system to be.
If you’re experimenting, Slack’s Workflow Builder gives you a starting point. If you’re very small and informal, statuses and spreadsheets may scrape by. But if you want an accurate, automated, and scalable solution, Vacation Tracker is the best way forward.
The truth is simple: PTO management done right isn’t just about keeping records. It’s about building trust, giving people the rest they deserve, and making sure the whole team can see what’s happening without friction. Vacation Tracker delivers exactly that, all without leaving Slack.
