To set up a shift pattern for employees who work irregular days/hours, you can create a separate Work Profiles for them and on the Working Rota tab, select all days on that they may work.
For example, if an employee could sometimes work on Monday, Tuesday, Thursday but the next week work Thursday, Friday & Saturday, this would allow them to book any day of the week off.
Just make sure that the hours in a day are correct so that any leave requests will deduct the correct amount of hours.
If you'd like to book out the non-working days on their Year at a Glance view, you can create a non-deducted Leave Type called "Non-working day". Ensure that this Leave Type allows for recurring requests.
You can then book out the non-working days on the calendar using this Leave Type so that their rota is reflected correctly.
