This can only be added in days, which makes it not much use.
If the policy is in Hours, then it takes an average of the working week and applies this.
You need to be able to add the actual hours as toil or other holiday, as this will normally be a specific time be 1 hr or 15 hrs etc.
The work around to go to the settings to change the balance. but then no record is created of the date/reason etc.
I have put this as critical, as the days/hours is a fundamental requirement that Sage HR needs to provide for it to be useable.
