It was a common question:
"Can I add a user that doesn't have an email address? I'm not fussed about the approval process. We have drivers on the road all the time, we just need to record their holidays on Timetastic along with the rest of our team."
Admittedly we never considered this use case when we first launched Timetastic, but today that changes, you can now add employees that don't have email addresses.
You add them through the normal process, just omit the email address field.
Another little improvement, we'll keep them coming!
