We want to register the vacation period in the HR Calendar for an employee who does not have a fixed number of vacation hours per year, is that possible?
Yes, you see that for example often for the Director / shareholder that also works in the company but has no agreement on how many vacations days he / she has.
In that case you can create a Vacation Time policy and choose 'Unlimited time' at 'Accrual method', see print screen below.
