Automated Digital Leave Requests

Submitting a leave request takes two minutes. Checking it takes longer: how many days does this person actually have left, and who else is away that week? The workflow answers both before the manager decides, then writes the approved leave into every system that is kept by hand today.

Context

The request is simple, the check is not

Three questions have to be answered before anyone can write “approved”, and each answer sits somewhere else. What is the balance today? Payroll knows. Who else is off that week? The team calendar, the shift roster, or a paper planner on the workshop wall. And what applies when two people want the same week? The team lead knows; it is rarely written down. None of the three answers travels with the request.

The first question is the hardest, because an entitlement is rarely a fixed number. It moves with a start date mid-year, a change from five days a week to four, carry-over from December, and sick days during leave that go back onto the account. The figure in the HR system is a snapshot: it knows the days taken up to the last month-end, not the ones already approved and still to come. Out of that gap come the two mistakes that show up every year – leave signed off in the autumn that no longer exists on paper, and days left over in December that the roster cannot absorb.

The other two questions belong together: who else is away can be counted, whether that is too many cannot. “One of you two has to be here” is a sentence in the team lead's head, not a rule a machine can test. It does not say whether “one” means anybody or the one person allowed to take the out-of-hours calls. Software can count absences, but only against a number somebody has committed to first. So we build that number first, then the route that applies it to every request without taking the decision away.

Use cases

Which absences are worth automating

We start with the request type that comes up most often at your company. Every further type later shares the same balance calculation and the same approval route.

Most common starting point

Ordinary annual leave

The most common case: several days in a row, somebody covering, and a manager who does not carry the balance in her head.

DatesCoverBalanceApproval

Single days, bridge days, half days

The 2nd of January, the Friday after a bank holiday: half the team asks for the same day, and arrival times start to matter.

Half daysBridge dayTimestampQuota

Shift work and minimum cover

Where a service desk or a production line has to keep running, headcount is not the point: two people present do not replace a switching authorisation.

Minimum coverQualificationRosterSite

Special and unpaid leave

A house move, a wedding, caring for a relative: separate allowances and evidence. Whether HR or the manager signs these off is your call.

Absence typeEvidenceApproval

Illness during leave, cancellations, changes

The case most likely to be left half-finished by hand: the days go back onto the balance, the calendar still shows a holiday.

Credit backCertificateFix the calendar

Year end, carry-over and expiry

From October, who still has how much left – plus the reminder to staff that an employer should be able to evidence later.

Example

One team, one leave year, one clash

Five people in a service team as of mid-July: what is approved, what is requested, how many days are left – and the week in which minimum cover breaks.

  • Week 31, 27 to 31 July: three absences meet, which would leave two of five people on duty. The third request is not rejected – it reaches the team lead with exactly this figure and the time it was submitted.
  • R. Feldmann, 12 days left: not a single request by mid-July. From the cut-off date you choose – 1 October in this example – the workflow reminds the employee and the manager, with the date in the log.
approved requested clashes with minimum cover Figure in a cell = working days

The telling part is not K. Anders' request but the row beneath it: both holidays approved for July were harmless on their own. Only the third request pushes cover below three – and you see that only if every request sits in the same view.

Illustrative extract from one leave year, shortened to five people and whole months. In practice the workflow counts day by day, using the public-holiday calendar of the site and each person's working-time pattern.

How it works

From the request to the calendar entry

  • The request arrives with its numbers

    A form in Teams, on the intranet or behind a web link asks for dates, absence type and cover. The working days come from the site's public-holiday calendar and the person's working-time pattern, not from the requester's estimate.

  • Balance worked out as of today

    Entitlement, carry-over and days taken come from your authoritative source. The workflow deducts what is approved but not yet taken and shows both: the source as it stands, and the position once every promise is counted.

  • Overlap tested against a written rule

    For every day of the requested period the workflow counts who else is away and compares that with your minimum cover per team, site or qualification. Blocked periods such as a stocktake or a shutdown sit alongside as a calendar.

  • Approval with a deadline, a reminder and a log

    The manager decides where she already works, with balance, overlap and submission time in front of her. How long she has and who takes over in her absence are our proposals, settled with you in the intro call. Each decision is logged with the data it rested on.

  • After approval the workflow writes

    An all-day entry in the team and Outlook calendars, a confirmation to requester and cover, an entry in time recording, roster and HR system. Cancellations and illness during leave run the same steps in reverse.

Limits

What a leave workflow will not fix

Four points we raise before quoting – the first is a reason to leave the project alone:

  • Below roughly twenty employees this rarely pays off. Where one shared calendar shows who is off when and the manager carries the balances in her head, €1,290 will not come back in saved minutes; a spreadsheet and a short conversation are the more honest tool. The case turns with shift work, several sites, or a cover level that has to hold.
  • The balance is only as good as its source. We do not recalculate entitlements, we carry them forward. Pro-rata entitlement for starters and leavers, a change of working pattern mid-year, parental leave, long-term sickness: the binding number stays in payroll. If it is wrong today, the workflow shows the difference – it cannot put it right.
  • The minimum cover is yours to set, not ours. One number per team, per site and per period, in shift work per qualification as well – that means meetings with your managers, not a settings page. It gets uncomfortable, because unspoken privileges come up there: who has had August for years, and why. We chair it and write down the outcome.
  • A human still decides who is turned down. Whether the colleague with school-age children takes priority over the one who stood back last year is not a rule that fits into a form. Expect some of your managers to experience this as a step backwards: a refusal that used to disappear into a corridor conversation now sits in the log, dated and open to challenge.

Questions & answers

Frequently asked questions about digital leave requests

No. A well-kept list in SharePoint or Excel works, as long as there is exactly one of them. It gets difficult when payroll, a spreadsheet and the team lead's memory each hold a figure and two disagree. Which source is authoritative we settle before we build. Where Personio or something like it is in place, we use its balances and write back.
Open requests count towards the cover check before anyone has decided on them – otherwise two managers approve the same week on the same morning. The manager sees both periods, their submission times and how many people would still be on duty. Whether the earlier arrival settles it is your call, not the software's. If the first is refused, cover for the second is recalculated.
We take the balances from your source at a cut-off date and add the leave already approved for the rest of the year – without it the cover check is blind through the first summer. Requests already on paper finish where they started. Entering that backlog is the real work of the introduction, and it lands with you. Starting shortly before the holiday season is the worst timing.
Under the German Federal Leave Act, days covered by a medical certificate go back onto the balance. Once HR records the certificate, the workflow corrects the account, shortens the calendar entry and tells whoever was covering. Without a recorded certificate nothing happens: crediting days back is a deliberate act. A rescheduled period is checked like a new request and can fail on cover in its new slot.
By default the team calendar says “away” and not why; special and unpaid leave stay between the employee and HR. The log records requests and decisions, not the behaviour of individuals. In co-determined companies, bring the works council in early: systems that make absences and decisions visible are usually subject to co-determination. Plan weeks for that, not days.
It can remind every employee and their manager from a cut-off date you choose, with the exact number of open days, and log the reminder with its date. Under German case law, leave only expires if the employer asked the employee to take it and warned of the expiry in good time. We supply trigger, wording and evidence; whether they are enough belongs with your legal advisers, not with us.

Practical guide

Where digital leave requests creates value in everyday work

The workflow captures dates and cover, checks defined rules, requests approval from the right person and updates calendars and teams after approval.

Three concrete operating scenarios to compare with your own process.
01

Approve standard leave

Request, cover and calendar overview are available to the manager in one view.

02

Identify team overlaps

Parallel absences are shown as guidance without making the decision automatically.

03

Communicate absence

Calendars and cover are updated reliably after approval.

A strong fit when …

Recurring office tasks follow clear rules, consume small blocks of time every day and should run reliably without replacing existing systems.

  • You handle recurring leave requests using repeatable rules.
  • The intake, target system and accountable business role can be named clearly.
  • Exceptions are allowed to remain visible and move to people deliberately.

Frequently asked questions

What decision-makers should know before starting

How does digital leave requests work in practice?
An employee submits a leave or absence request. The workflow then validates the required data, runs approved steps and routes exceptions to the responsible person with context.
Which systems can be connected?
Typical integrations include Microsoft Teams, Microsoft Forms, Outlook, SharePoint, Personio, HR-System. The decisive factors are a stable interface and clearly defined ownership of each data field, not a specific tool.
Which tasks deliberately stay with the team?
Employment-law decisions, special leave, conflicts and authoritative balance calculations remain with HR and management.
How is the automation introduced?
We choose one frequent, tightly scoped task, document its intake, destination and exceptions, and test it with a small user group. A tightly scoped first process typically takes 2–4 weeks; scope, interfaces and approvals determine the actual plan.
How can the benefit be measured?
Before implementation we record volume and current handling time. After launch we also compare Handling time, Open exceptions, Manual transfers. The calculator on this page is a transparent estimate, not a promise.
