We do get asked about dual/second/2 tier authorisation levels. Where companies want to have absences approved by 2 (or more) members of staff.
It's not something available on Timetastic sorry, but let us explain why.
In some respects dual authorisation can be attributed to the situation of imperfect knowledge. A product of the traditional paper based system where you might not have all the information about who else is off when and what requests are pending, so a second set of eyes is important.
But with Timetastic you have perfect knowledge when making your decision, all the requests are there to see, plus you have controls such as you can't exceed your allowance, you can set a max absent per department, you can lock periods where you specifically want people in.
So if you implement those controls then we hope a second level of authorisation isn't necessary any more - another time saving.
It might well be that the two tier approval system you currently employ could be a significant saving.
Apologies if that doesn't suit your situation though, no doubt there will be unique exceptions.
