So the company currently has 3 working shifts,

Shift 1: 0600-1400 hours

Shift 2: 1400-2200 hours

Shift 3: 2200-0600 hours

All shifts have 8 working hours.

Currently Odoo by default only allows for a morning and afternoon shift, of which it only covers Shifts 1 and 2. However, how do I account for the third shift? Is there an option or something that allows me to have three shifts in or do I have to alter the code to allow for a third shift? 

If I do have to alter the code, how would I go about it and what kind of code do i have to add in order to have a third shift?

Thanks
