Calculated Employment Date (WTTA)
Retrieve the legally required employment date from MSF and use it in employment contracts and documents. F106012 | 2026-05
Introduction
Under the Dutch WTTA regulation, the employment date of a candidate must be determined again when the candidate is re-employed. For this reason there is a new field, ‘calculated employment date’, for which the date is retrieved from MSF. The logic of the old field ‘Employment Date’ has been removed, because it does not comply with the WTTA. The old field stays available, because customers use it in their own way.
Who is this feature relevant for?
- Staff who create and manage employment contracts
- Administrators who maintain document templates
- Application administrators with their own contract flows
Benefits at a glance
- The calculated employment date follows the WTTA rules, including re-employment
- The date is retrieved from MSF automatically
- Earlier periods of employment from the contract history can be included
What is new
- A new field ‘calculated employment date’ has been added to the candidate.
- This field is filled by the ‘BC contract batch’. The advice is to run this batch once a day to keep this data up to date.
- There is a new XML tag for generating employment contracts: ‘Calculated Employment Date’.
- When an employment contract is generated, the calculated employment date is retrieved from MSF immediately and then also written to the candidate.
- This is also possible if the contract has not yet been synchronised to MSF, as long as the start date and the business unit are filled.
- In the standard contract wizard, the field ‘calculated employment date’ has been added for information. If it is used, this date is also written to the candidate immediately.
- The contract history has a new checkbox, Include For Employment Date. Select the checkbox to include an earlier period of employment in the calculation. The checkbox is off by default.
Note: All document templates for generating employment contracts must be changed. The new field ‘calculated employment date’ must be added to all existing templates to comply with the WTTA.
The existing field ‘Employment Date’ on the candidate is no longer filled automatically, because the earlier logic does not comply with the WTTA. This field does remain available for your own use. (For example, to record the original employment date.) For this reason, it may be necessary to remove this field from the existing templates.
Flows
In flows, the new action ‘Calculate Employment Date (MSF)’ can be used to retrieve the calculated employment date, so that it can be used in your own contract flows. Note that writing this date to the candidate must then also be included in the flow.
Set-up / Implementation time
Because all document templates for generating the employment contracts must be checked, this depends entirely on the number of templates used.
