In many companies, talking about working hours means talking about weeks. But the reality of shifts and collective agreements is usually in annual terms: hours to be worked in a year, irregular distribution, adjustments for bank holidays and annual leave. Without a system, tracking becomes a mix of spreadsheets and 'gut feeling'.
1) The difference between planned hours and actual hours
Planning is one thing and execution is another. Annual working hours are understood by comparing theoretical hours (according to calendar and contract) with actual hours (according to records). If you do not have both, you cannot know whether a team is doing more, less, or whether there is a planning problem.
Example: an employee has 40 theoretical weekly hours, but due to changes and extensions accumulates 6 overtime hours per month. At year end, the deviation is large and appears too late. With monthly tracking, it is corrected sooner.
2) Calendar and absences: where the calculations break down
Bank holidays, annual leave, personal leave, and sick days change the count. If managed outside the system, the annual calculation becomes disorganised. Integrating absences with shifts and records avoids duplications and errors.
An example: if a person is on holiday, their theoretical working hours change and this should not be compared with an 'unworked shift' as if it were absenteeism. Documenting the absence avoids misinterpretations.
3) Irregular distribution: clear rules and communication
When the company needs to move hours between weeks or months, the risk is doing so without transparency. Define how it is distributed, with what advance notice, and how it is recorded. Irregular distribution without rules usually ends in conflict.
Example: during peak season, weeks with more hours are planned, and during the low season, compensation is made with fewer hours. If the system shows the balance and the planning, the team understands the reason and tension is reduced.
4) Simple example: monthly balance tracking
Define a monthly report by employee and location: theoretical hours for the month, actual hours, balance, and main reason for deviation (overtime, changes, on-call duties). With this, HR and Operations speak the same language.
If a location consistently accumulates a positive balance, it is not 'that people want to work more': it is usually undercoverage or inefficient processes. The balance guides you to the root cause.
5) Win-win: control without stress
For the company, tracking annual hours avoids year-end surprises and allows better sizing. For the worker, it provides transparency: they know what is expected and what has been done, without disputes.
The win-win occurs when the balance is managed proactively: small monthly corrections instead of major annual conflicts.
