Everything you need to run leave properly.
Otium One handles entitlement, pro-rata, carry-over, and TOIL automatically, even for the complex cases. No modules to unlock, no add-ons to buy: you get the full feature set, a guided setup that has you running in minutes, and built-in help on every screen.
Leave management that takes care of the rules
Entitlement, pro-rata, carry-over and TOIL — calculated automatically, even for complex working patterns, so HR doesn’t have to maintain a spreadsheet for it.
Entitlement & carry-over
- Starters, leavers, and part-time schedules — entitlement and pro-rata recalculated correctly, every time.
- Carry-over between holiday years, on whatever policy you set.
- Statutory carry-over protection (WTR reg 13): leave blocked by sickness or family leave carries over separately, usable for 18 months after the leave year ends.
- Bookings that cross your leave-year reset are split into two requests for you, each charged to the right year.
Leave types & allowances
- Custom leave types beyond annual leave and sickness — configure your own with the rules that fit.
- Leave banks — a shared allowance (like "Training") that several leave types draw down together.
- Unlimited-allowance leave types, for when a cap doesn’t make sense.
- Time off in lieu (TOIL): grants, balance tracking, and a booking guard that stops a balance going negative.
Irregular & zero-hours workers
- 12.07% accrual calculated automatically, as the Working Time Regulations require for leave years from April 2024.
- Leave charged at average hours over the statutory 52-week reference period, looking back up to 104 weeks.
- Staff submit their own hours each pay period for an admin to approve.
Effortless leave management
Everything employees and managers need to request, approve, and stay on top of leave, without chasing anyone.
Approvals
- Single or dual approval per request, with bulk approve and reject for working down a busy queue.
- Approval delegation — approvers hand off their own duties while they’re away, with an end date or left open-ended.
- Real-time approvals queue — new requests appear without a page refresh.
- Internal comment threads on a request, visible to admins and approvers only.
Changes & sickness
- Approvers edit a booking’s dates directly; employees request a date change on approved leave for their approver to confirm.
- Book the day after an existing absence and Otium One offers to extend it instead — one illness stays one absence.
- Return-to-work interviews for sickness, recorded on the request itself.
Everyday use
- A notification bell with a live unread count, plus a full paged history.
- Works on your phone — install it to your home screen and get push notifications.
- A keyboard command palette (⌘K / Ctrl+K) to book leave or jump to any page.
- Hours-mode booking for shift and clock-time working patterns, everywhere or for an individual.
The moments a spreadsheet can't handle.
Plans change. So can the dates.
Edit an existing booking instead of cancelling and rebooking — the balance and clashes are rechecked as you go.
Return to work, on the record.
Record the interview on the sickness request itself, with the wall chart flagging who’s still waiting for one.
In your pocket.
Install it to your phone’s home screen to book, approve, and get notified on the go.
Total visibility, wherever you look
See who’s off, spot cover gaps before they happen, and pull the numbers HR and payroll actually need.
Wall chart
- Who's off, by day, across your whole team or the wider business.
- Updates in real time — approve or cancel a request and watch the chart change.
- Drag across any date range to book leave.
- A 6-week rolling view or a full calendar month, with your choice of grid lines, icons, and density.
- Minimum staffing levels — warn or block bookings that would leave a team under-covered.
Reports
- Bradford factor with trend sparklines, staff utilisation, leave bank and TOIL usage, irregular-hours accrual, and leaver history.
- Automatic risk alerts to your admins when someone’s absence trend worsens.
- Payroll or Bradford factor reports emailed weekly or monthly — including to your payroll processor, with no login needed.
Data in & out
- Every report exports as CSV or a print-ready PDF, including a dedicated payroll export.
- Bulk CSV import for users and leave history, with one-click undo if a batch needs reversing.
- iCal feed — subscribe to your approved leave from any calendar app.
