Suggest employees for a shift. This is a synchronous API that returns a list of employees who are either recommended or not recommended taking into account hard constraints such as overlapping shifts and soft constraints such as unavailability, leave, not trained, not preferred, stressed, and onboarding status. The request must include required fields such as start/end times, employee and area. If the list is greater than 100, a cursor will be returned to paginate the remaining results. Optional filters can be provided to filter the employees considered for the shift.
