Types Of Authorised Absence, Explained Properly

Types Of Authorised Absence: the short answer

Most explanations of types of authorised absence either restate a legal definition or dissolve into generalities. Here is the practical version, followed by the detail that actually changes what you do.

The core idea matters because of a specific operational consequence: it determines how a day off is recorded, whether it comes out of an allowance, and what the employer owes. Get the classification wrong and the error propagates into balances, payroll and — for anyone who leaves — a final settlement figure.

That is why the definition is worth being precise about. It is not a terminology exercise; it is the input to arithmetic that has to be right.

A worked example: what actually carries over

UK statutory leave splits into two parts, and they behave differently. Of the 5.6 weeks in gov.uk holiday entitlement guidance, four weeks derive from retained EU-era working time rules and 1.6 weeks are the domestic addition.

An employee with the statutory 28 days has 12 days remaining on 31 December. Your policy allows five days of carry-over.

They carry five days into January, and 7 days lapse. That is lawful for the 1.6-week portion, which can be restricted, but the four-week portion carries stricter protections: it generally cannot simply be extinguished if the worker was prevented from taking it — for example through sickness absence or because the employer never gave them a genuine opportunity to take it. Acas guidance is the practical reference here, and this is exactly the point where you should take advice rather than rely on a policy template.

The operational lesson is narrower and more useful: a December balance of 12 days was visible in October, and in September. Carry-over disputes are almost never a December problem. They are a September problem that nobody looked at.

Run the check in Q3. Anyone sitting above roughly half their allowance with a quarter of the year left needs a conversation, not a policy.

How it works in practice

In a UK context, the reference points are gov.uk holiday entitlement guidance for the statutory position and Acas for practical application. The statutory floor is 5.6 weeks of paid holiday per leave year, and most questions about types of authorised absence resolve into: does this sit inside that entitlement, alongside it, or outside it entirely?

Three tests usually settle it. Is the time paid, and by whom — employer, statutory scheme, or unpaid? Does it reduce the annual leave balance? And does it need to be recorded separately for reporting or compliance purposes?

Answer those three and the correct treatment follows. Skip them and you get the classification that was easiest to click.

Who it applies to, and who it does not

Employment status is the first filter. Employees and workers both accrue statutory holiday; genuinely self-employed contractors do not. The category that causes trouble is the one in between — people labelled as contractors who function as workers — because status is determined by the reality of the arrangement rather than the label on the agreement.

The second filter is the working pattern. Full-time staff on a fixed five-day week are straightforward. Part-time, term-time, compressed-hours and zero-hours staff each need their entitlement derived from their own pattern, and the further a pattern sits from the standard week, the more likely the calculation is wrong somewhere.

The third is length of service. Statutory entitlement does not increase with service, though many contracts add days after a qualifying period. If yours does, be clear whether the increase applies from the anniversary or from the start of the next leave year — both are defensible, only one is what your spreadsheet is doing.

Recording it correctly

Once the classification is settled, the record needs to carry enough information to reconstruct the decision later.

That means, at minimum: what was requested, when, who decided, what was decided, and — where a request was refused — why. The reason field is the one people skip and the one that matters in a dispute.

It also means the balance has to be derivable from the bookings rather than maintained separately. A balance typed into a cell is an assertion; a balance computed from approved bookings is a fact. When the two disagree, and over a year they will, only the second one can be defended.

The practical test: pick a booking from eight months ago and try to establish who approved it and on what date. If that takes more than a minute, the record is not doing its job.

Common misconceptions

That it is discretionary when it is not, or mandatory when it is not. Both errors are common and both are expensive in different ways.

That the same rules apply to part-time staff proportionally by days. Entitlement is defined in weeks, and days are derived from the working pattern — which is why the shortcut of scaling 28 breaks for anyone irregular.

That it can be handled informally. Informal handling works right up to the point where someone leaves, or disputes something, and then the absence of a record is the entire problem.

That the policy is the system. The system is the system. If your policy says one thing and the tool holding the balances does another, people will follow the tool.

Where LeaveKit fits

LeaveKit is a leave management tool for UK teams of roughly 5 to 50 employees, and it is worth being precise about what it does and does not do.

What it does: month, week, 30-day and day views with department filter, hover detail cards, holiday and birthday markers; date range with half-day start/end and live working-day calculation; and — the part that motivated it — warns at booking time when teammates are already off on the same dates (/api/leave/conflicts). It also handles overtime entry logging at /toil, converts logged hours into toil balance, CSV reporting, an iCal subscription feed, and public holiday calendars for 11 countries with the UK dates checked against gov.uk for 2026 to 2028.

What it does not do, stated plainly because buying decisions are made on the gaps: there is no Slack integration, no two-way Google or Outlook calendar sync (the iCal feed is one-way), no payroll or Xero connector, no public API, and no SSO. The mobile app is built but not yet released. If any of those are requirements today, LeaveKit is not the right tool for you yet.

Commercially, LeaveKit is in early access with a 30-day free trial and no card required. Public pricing is not published yet. You can also open the demo workspace without signing up at all, which is the fastest way to judge whether the wall chart matches how your team actually thinks about coverage.

Frequently asked questions

How much holiday are UK employees legally entitled to?

The statutory minimum is 5.6 weeks of paid holiday per leave year, according to gov.uk holiday entitlement guidance. For someone working five days a week that is 28 days, and employers are permitted to count the eight UK bank holidays within that total rather than in addition to it. Part-time employees get 5.6 weeks of their own working week: three days a week gives 16.8 days. The contract must state whether bank holidays are included.

Can an employer refuse a holiday request?

Yes, an employer can decline a specific request, subject to notice requirements. What an employer cannot do is operate in a way that prevents someone taking their statutory entitlement at all. In practice, a refusal is far easier to defend when it comes with a concrete reason — a stated minimum cover level for that team on those dates — than when it is attributed to unspecified operational requirements. Acas publishes guidance on handling refusals.

What happens to holiday that has not been taken by the end of the leave year?

That depends on your policy and on which part of the entitlement is involved. Of the 5.6 weeks, 1.6 weeks can generally be restricted more tightly, while the four-week portion carries stronger protections — particularly where someone was prevented from taking it through sickness or because they were never given a real opportunity. Set a carry-over cap in policy, and run a balance check in the third quarter rather than in December.

Is LeaveKit free?

LeaveKit is in early access with a 30-day free trial and no card required. There is no permanent free tier and public pricing has not been announced yet. The trial is the full product: wall chart, booking with half-days, conflict warnings, approvals, TOIL logging, CSV reports and public holiday calendars. There is also a demo workspace at /demo that needs no sign-up at all.

Does LeaveKit integrate with Slack or sync with Google Calendar?

No Slack integration exists today, and calendar support is a one-way iCal subscription feed rather than two-way sync — leave appears in Google Calendar or Outlook, but changes made there do not flow back. There is also no payroll connector, no public API and no SSO at present. If any of those are firm requirements, LeaveKit is not the right fit yet, and it is better to know that before a trial than during one.

Try it on a real month

The fastest way to judge any leave tool is to run one real month through it. LeaveKit has a demo workspace that needs no sign-up, and a 30-day trial with no card required.
