Rosters that work round the clock.
Klacks plans wards and shifts without gaps — keeping the 6-month reference period for the 48-hour OWTA limit, compensatory rest under WRC Code of Practice COP8, and the consecutive-days requirements of the NCHD Agreement all in view. Installed on your premises, so patient data is stored on your own servers.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script. They only illustrate the product – you do not need to know or be able to read them. In your own installation you enter your own data, and the interface is multilingual.
6-month reference period, compensatory rest and NCHD requirements
6-month reference period for the 48-hour limit
For medical staff, Section 15 of the OWTA 1997 allows a reference period of 6 rather than 4 months for calculating the average 48-hour week — almost impossible to track by hand across changing shift patterns.
Compensatory rest under COP8
If a rest period is shortened, the WRC Code of Practice on Compensatory Rest Periods (COP8) requires a compensatory rest period — when and how it is granted must be documented.
NCHD Agreement: 10 consecutive duty days maximum
The HSE/IMO NCHD Agreement 2022, in force since January 2023, mandates rest for non-consultant hospital doctors after a maximum of 10 consecutive duty days, together with compensatory payments.
Your finished shift plan in three steps
Install
Klacks is installed on your own infrastructure — via Docker; allow about half an hour for the first start.
Adjust rules
Public holidays and rest periods come preconfigured for your country, surcharges where defined for your country — and you can adjust them anytime.
Plan automatically
Klacks builds shift plans, flags conflicts and optimizes routes — with an AI assistant if you want.
How Klacks takes the load off hospitals in Ireland
From seamless 24/7 cover to compensatory rest — it all fits together.
Seamless 24/7 cover
Day, evening and night shifts across every ward — Klacks flags every gap instantly and fills it automatically on request.
6-month reference period calculated automatically
Klacks monitors the average 48-hour week live over the rolling 6-month period you have configured, as provided for medical staff under Section 15 OWTA, and warns before the average tips over — correctly factoring in each employee's start date. On request, Klacks blocks any breach in the automatic planning paths (e.g. wizard, suggestions, substitution); in manual planning, Klacks warns.
Compensatory rest under COP8 planned in
If a rest period is shortened, Klacks automatically suggests the appropriate compensatory rest period under WRC Code of Practice COP8.
NCHD duty days kept in view
Klacks counts consecutive duty days for non-consultant hospital doctors and warns before the 10-day limit from the NCHD Agreement 2022 is exceeded.
Installed on your premises: data stored on your servers
Klacks runs on your infrastructure. Staff and patient data are stored on your servers — with a locally hosted AI model, no AI request goes to an external AI provider.
Klacksy understands your request
"Fill next week's night shifts on Medicine" is enough — Klacksy starts the planning, Klacks takes qualifications and rest periods into account.
What Klacks can do — in real recordings
Short videos from the running app, sorted by topic. Choose a chapter; only the video of the open chapter ever plays.

- Klacksy helps you get it right in every one of these cases: describe your rule in the chat in your own words, for example “Sundays earn a 50% surcharge.” — Klacksy asks follow-up questions, shows a preview and only saves once you confirm.
- Klacksy also creates scenarios and starts planning inside them — tell it in the chat, for example: “Plan Winterthur from November 2 to 8.”
- Klacksy, the built-in AI assistant, can also do all of this for you on request — for example, tell it in the chat: “Add expenses of 24.50 for Mia on October 6.”
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 itselfUnlike 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.
- Combining the Republic and Northern IrelandA 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.
- Active or informational onlyYou decide per calendar whether a holiday affects hours & surcharges — or simply appears as a reminder.
It all comes down to the settings
Klacks offers countless ways to calculate rules and hour credits for nights, weekends, public holidays and overtime — exactly the way your contracts and company agreements require.
- Nights and weekends You set the night window and the surcharge rates yourself, and choose up to three weekend days — as a multiplier that is added to the hours worked as a time credit in hours.
- Public holidays and overtime A separate public-holiday rate, and overtime per day or per week in up to three tiers. When several surcharges fall on the same hour, the highest one applies — or all of them add up.
- Your own calculation with a macro If that is not enough, a macro does the maths: a short script using weekday, time of day, public holidays and contract values — with conditions, loops and functions of your own.
- Scheduling rules Rest periods, maximum daily and weekly hours, consecutive working days, free Sundays or hour caps per period — each one as a warning or, in automatic planning, as a block.
Rule violations: Klacks warns you instantly
Klacks flags time collisions, rest periods that are too short, too many consecutive working days and work on holidays right as you plan — as an error or warning in the error list.

Multiple wards, one view of COP8 and NCHD
Every ward has its own staffing rules. Klacks plans them together, calculates the 48-hour limit over the 6-month period, and automatically suggests the appropriate compensatory rest under COP8 whenever a rest period is shortened — the director of nursing can see at any time where things are getting tight.
