Workforce scheduling where you stay in control.

Klacks rosters shifts automatically, checks OWTA rest periods in real time and keeps an eye on Banded Hours entitlements — open source, installable on-premise, and with the AI model of your choice. That way staff data stays exactly where your Data Protection Commission (DPC) wants it: in-house.

OWTA, Banded Hours and the question of data sovereignty

gavel

Keeping the OWTA weekly working-time limit under control

The Organisation of Working Time Act 1997 caps average working time at 48 hours a week, with a standard reference period of 4 months. An extension to 6 months applies only to specific activities such as security or healthcare — tracking this by hand is error-prone.

Banded Hours & shift notice

Under Section 18A OWTA, employees can apply for placement in a band of hours if their contracted hours don't reflect reality; the employer then has 4 weeks to respond. Section 17 OWTA also requires at least 24 hours' advance notice of start and finish times where the roster isn't fixed.

cloud_off

Data sovereignty instead of a third-country cloud

The Data Protection Act 2018 implements the GDPR in Ireland, with the Data Protection Commission (DPC) as the supervisory authority. Especially when it comes to AI features, many businesses have to ask whether staff data may go into a third-country cloud at all.

Rules & Calendar

Uniform nationwide, split at the border

The Republic of Ireland has no public holidays at county or municipal level: all statutory holidays apply uniformly nationwide under the Organisation of Working Time Act 1997. For businesses with ties to Northern Ireland, though, what applies across the border still matters — a completely separate holiday regime is in force there.

    No patchwork within Ireland itself Unlike many other countries, the Republic of Ireland has no public holidays at county or municipal level — the Organisation of Working Time Act 1997 sets all statutory holidays uniformly nationwide. Northern Ireland, as part of the United Kingdom, has an entirely separate regime.
  • layers
    Combining the Republic and Northern Ireland A business in the border region — say, in Dundalk (County Louth) or Letterkenny (County Donegal) — or with locations in Dublin and Belfast keeps both calendars side by side: St. Brigid's Day (the first Monday in February) and the June bank holiday in the Republic, Orangemen's Day (12 July) in Northern Ireland.
  • tune
    Active or informational only You decide per calendar whether a holiday affects hours & surcharges — or simply appears as a reminder.

How Klacks takes the load off Irish businesses

From automatic rest-period checks to your own infrastructure — it all fits together.

gavel

Weekly working-time limit monitored automatically

Klacks monitors the rolling 48-hour average live over the reference period set out in OWTA Section 15, and warns before the limit is exceeded — including the sector-specific extension to 6 months for security and healthcare, correctly factoring in each employee's start date. On request, Klacks can hard-block any breach — a new violation can then only be saved with documented supervisor approval.

bedtime

Rest periods observed automatically

The daily rest period of at least 11 consecutive hours (Section 11) and the weekly rest period of at least 24 hours (Section 13) are monitored in real time — breaches simply never occur.

campaign

Shift notice with 24 hours' lead time

Klacks automatically checks the minimum lead time for roster publication: the 24-hour advance-notice period for start and finish times required by Section 17 OWTA is stored as a publication deadline, and Klacks warns if a roster would be published too close to the deadline.

fact_check

Banded Hours applications documented

Klacks records actual hours worked over 12 months, so an application for Banded Hours under Section 18A OWTA can be answered cleanly within the 4-week deadline.

On-premise: full data sovereignty

Klacks runs on your own infrastructure, and you choose the AI model — including locally hosted, with no staff data ever transferred abroad.

Klacksy: rule-based, not a black box

The built-in AI assistant Klacksy schedules by voice command — transparently, based on defined skills and rules, not as an opaque AI decision.

science

Test plan changes risk-free

Before a plan change goes live, you can run it through as an isolated copy — the 11-hour daily rest period (Section 11) and surcharges are calculated live exactly as in the real plan. Only once everything checks out do you apply the variant; until then, your live schedule stays untouched. This lets you prepare a suitable scenario in advance for foreseeable situations — such as a staff member calling in sick or a sudden spike in orders — so you're ready to act immediately when it matters, instead of improvising under time pressure. There's no artificial limit on the number of scenarios — create as many as your planning needs.

AI assistant

Klacksy: the assistant built into your team's workflow

Klacksy isn't a bolted-on marketing chatbot — it's embedded directly in the Klacks interface. Staff and schedulers ask about shift times via chat, request shift swaps, or clarify availability. A built-in skills and rules system ensures Klacksy only ever makes transparent suggestions — never a black-box decision. For businesses with strict data protection requirements, the AI model can also be hosted locally, which matters with the DPC in mind too.

In practice

24 hours' notice, one view

A roster changes at short notice. Klacks automatically checks the 24-hour advance-notice period under Section 17 OWTA against the stored publication deadline, while keeping the 11-hour rest period in view — no manual recalculating required.
