Time off, one Slack message away
A Slack leave tracker your team never has to leave
Request, approve and see time off inside Slack — while a full leave system keeps balances, accruals, public holidays and reports accurate in the background.
Absenca puts a full leave tracker inside Slack: employees request time off from a shortcut, managers approve from an interactive message, and an optional daily summary shows who's away — while accruals, balances and public holidays stay accurate underneath. If your company lives in Slack, a leave tracker that lives anywhere else will quietly stop being used: people forget the login, managers miss the email, and the spreadsheet creeps back. Absenca's Slack integration puts the whole everyday flow — request, approve, who's off today — inside Slack itself, so tracking time off stops being a separate chore.
Underneath, it's not a toy bot: every Slack action writes to the same leave system as the web app, with real accruals, carry-over, per-office public holidays and an audit trail. And the integration is included on every plan — Absenca is free for up to 15 people, then a flat $0.75 per user per month.
Request leave from a shortcut
Pick a leave type and dates, see your remaining balance as you book, and submit — without opening another app or remembering another password.
Approve from the message
Managers get an interactive Slack message for each request and approve or decline in one click, from desktop or mobile.
Daily who's-off summary
An optional morning post to the channel you choose lists everyone away today, so stand-ups and staffing plan themselves.
A real leave system underneath
Accruals, carry-over, half days, blackout periods, public holidays for 190+ countries and full reports — every Slack action keeps them accurate.
How the Slack leave tracker works
Connect your Slack workspace to Absenca once, and map people to their Slack accounts (new joiners can self-link the first time they book). From then on an employee requests time off from a Slack shortcut: choose the leave type, pick the dates, see the live balance, submit. The request routes to the right approver automatically.
The approver gets an interactive message — request details, dates, remaining balance, any overlap with teammates — and taps approve or decline. The employee is notified instantly, the shared calendar updates, and the balance adjusts. Nobody chased anyone, and nothing needs re-typing later.
If you want ambient visibility, switch on the daily summary: a short morning post to a channel of your choice listing who's away today and this week. Teams that run stand-ups in Slack usually pin it there — the "is anyone out today?" question disappears.
Why chat-first leave tracking actually sticks
Adoption is the hard part of any leave tool. A tracker that requires a separate login gets used by HR and ignored by everyone else, and the moment employees stop self-serving, the admin is back to being a human middleware layer. Putting requests and approvals in Slack removes the friction that kills adoption: there's nothing new to open, nothing to install per user, and approvals happen where managers already are.
Because Absenca records every chat action against the same balances, policies and audit log as the web app, the convenience costs you nothing: HR still gets accurate accruals, exportable reports and a defensible history — see all features for what runs underneath.
Set it up in a few minutes
1) Create your free Absenca account. 2) Open Settings → Integrations and choose Connect Slack, then approve the permissions on Slack's consent screen. 3) Map your members to their Absenca profiles — or let people self-link on first use — and optionally pick a channel for the daily summary. That's the whole setup — our step-by-step Slack time-off bot guide walks through it.
The Slack integration is included on every plan, free tier included: free for up to 15 people, then $0.75 per user per month. There's no per-integration fee and no card required to start.

Frequently asked questions
- Is there a free leave tracker for Slack?
- Yes. Absenca's Slack integration is included on the free plan, which covers up to 15 people with the full feature set — requests, approvals, balances, public holidays and the daily who's-off summary. Beyond 15 people it's a flat $0.75 per user per month.
- How do employees request time off in Slack?
- From a Slack shortcut: pick the leave type and dates, see the remaining balance, and submit. The request goes to the right approver as an interactive message, and the employee gets an instant confirmation once it's decided.
- Can managers approve leave directly in Slack?
- Yes — each request arrives as an interactive Slack message with the details and any team overlaps, and one click approves or declines it. The calendar, balances and reports update immediately.
- Does it post who's off today to a channel?
- Yes, optionally. Absenca can post a short daily summary of who's away today and this week to any channel you choose — most teams point it at their stand-up or team channel.
- What about teammates who don't use Slack?
- Everything works from the web app and email too. Slack is a convenience layer on top of the same system, so mixed teams — some in Slack, some not — stay perfectly in sync.
