Recognising that the assignments overlap requires another check. I build scheduling screens that validate the person, role and time interval while keeping draft plans separate from published rotas. Staff can see which version is current. Planners can see the conflicts that need a decision before the plan is released. ## Example: two overlapping shifts for Ece In the illustrative plan, Ece works Monday from 08:00 to 16:00. A second assignment runs from 12:00 to 20:00. The application identifies the four-hour overlap between 12:00 and 16:00 and holds publication until the conflict is resolved. Can is available from 12:00 to 20:00. Availability may also depend on the required skill or branch, not merely an empty calendar. The revised assignment is checked again before the rota is published. ## When a standard scheduling product is enough A ready-made workforce tool may already support standard shifts, leave checks and staff notifications. A small team with one planner may also manage well in a spreadsheet. Custom development is useful when branches apply different assignment rules or staff availability depends on several operational systems. Approved leave from an [employee leave application](https://oguzerol.com/en/employee-leave-tracking-app/) can feed the checks. The effect of a pending leave request is defined separately. ## Conflicts beyond two rows on a calendar A shift crossing midnight needs a complete start and end date. It cannot be treated as two clock values on the same day. Where branches use different time zones, the displayed time basis must also be clear. If two managers edit the plan, one person’s save should not silently overwrite the other’s changes. The application identifies a changed version and asks the planner to review the current assignments. Required headcount and skills can be checked per role. An unfilled role remains visibly open; the system should not assign an unsuitable person merely to fill the grid. Working-time and rest rules follow the policy supplied and confirmed by the organisation’s responsible team. The application is not presented as a universal guarantee of employment-law compliance. ## From draft to published rota A planner works on a draft without presenting it to staff as a confirmed assignment. Publication reruns the relevant checks. Any notifications identify the version they relate to. Delivery can include a weekly planning view, each employee’s own rota, an open-role list and [record change history](https://oguzerol.com/en/record-change-history/). Sending a notification is not automatically treated as proof that an employee has seen the change. I begin with a representative week, the role list and the conflicts you need to prevent. Tests cover overlaps, leave, overnight shifts and simultaneous edits. The handover defines how new branches, shift types and policy changes are maintained. ## Frequently Asked Questions ### Can employees swap shifts? They can submit a swap request. Both employees’ availability and the role requirements are rechecked, with manager approval where needed. ### Must the application generate the entire schedule? No. A first version can check a manually prepared rota. Automatic scheduling suggestions require a separate set of priorities and constraints. ## Discuss your workflow [Share a representative weekly rota and the conflicts you encounter](https://oguzerol.com/en/contact/). We can start by defining the errors that should be caught before publication.

Work-hour packages Tell me about your business and what you need on WhatsApp or by phone; we agree on **a work block of somewhere between 5 and 40 hours** and I start doing what is needed. What you get is not a calendar window — it is net working hours spent directly on your business. I can use 40 hours working three days straight, or deliberately spread it out and finish it over a year — whatever the work calls for. I do not spend my time estimating how long something will take, I spend it doing the work; every hour I spend leaves a lasting result in your business. We keep going for as long as you find it useful. WORK BLOCKS ## Why not monthly? Is 40 hours a week? On a fixed monthly fee both sides are watching the wrong thing: you watch a fixed cost, the other side watches how many more contracts like this they can line up. Working by the hour puts us both in front of the same thing — the real value of the work that got done. I know not having an upfront answer to "how much will this cost in total?" is the natural cost of this model. But instead of paying a fixed fee for months to a setup that is not producing results, you only pay for the qualified time spent on your work — and you see exactly where that time went, start to finish. That is why my clients keep coming back. 5hours300€ + VAT60€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%205-hour%20work%20block.) 10hours500€ + VAT50€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2010-hour%20work%20block.) 20hours800€ + VAT40€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2020-hour%20work%20block.) 40hours1,400€ + VAT35€ per hour[Choose this block](https://wa.me/905496546489?text=Hi%2C%20I%27d%20like%20info%20about%20the%2040-hour%20work%20block.)
