[SOLVED] How to use Leave or Absence correctly for different days

Because my company works 24 hours 7 days a week my staff are rostered to work on different days each week. This means that they days off are always different each week, each month and each year.

I cannot create a new calendar for them as this means every week, every month and every year they always need new calendars because their days off are always different.

So I want to know how to use the Leave Days or Leave Absences so that when planning I can put a day of leave and not have ProjeQtor plan work on the day that they are rostered not to work. How can I do this?

What do you mean by

Then go to the "absences" screen and correct what should be one by one.

How do I do this. The online manual is not easy to understand.

It is too confusing. I go to Absences and I cannot press on any button. It keeps telling me I have to make an administrative project and while I know how to do this, I don't need to create an administrative project as my workers are developers.
