Employment Rate of employees - Holiday off

Employment Rate of employees - Holiday off

Hey guys


I didn't find out yet how to set this up:

First Issue:
Each employee has a certain employment rate.
This varies from 100% - 20% (most employees are 100% though)

We need to store the employment rate of each employee on the user. Is there a predefined field for this or do I need to set one up myself?

Second Issue:
Our company holiday policy is 25 Days for a 100% employed employee. If an employee has an employment rate of 80%, he's only eligible for 80% of the 25 days = 20 days.

Is there a native functionality to automatically calculate this?
(formula is simple: (25/100) * Employment Rate = Available Holidays in Days)
