As per this link, shift management allows for shift rotation but the current configuration for shifts DO NOT reflect on a calendar on the desktop when that SHIFT day is considered an OFF day. According to SHIFT setup, we can only create a weekend setting to reflect a day per week that they would not be on schedule. Secondly, ONLY one shift can be assigned per employee per week. Many times with hybrid workers shifts vary by DAY not week. Since the Attendance module shift management in the "Attendance Calendar" menu does not provide for reflection of DAY Shift variances or that OFF shifts should be reflected as "OUT" not on "Weekend" needs updating. Since most Zoho APPS get updates quarterly and this has app has not been updated to be reflective of common requirements for Modern HRIS systems. Please update this immediately or at least schedule to do so. I would hate to leave Zoho for our HRMS as this is a simple upgrade as you already have an application called SHIFTS.
