Not every business assigns each person a fixed shift. Tanca has two mechanisms for flexible schedules: shift suggestions (the system proposes open shifts for employees to take) and crews (groups that rotate on a fixed cycle).

What is an open shift

An open shift is a shift that has been created but not yet assigned to anyone; it appears in the first row of the Scheduling grid. You create an open shift when you know you need more people but haven't decided who — employees register to take it, and the manager approves afterward.

Shift suggestions

Go to Settings › Scheduling › Smart Shift Assignment, the Shift Suggestions tab, and click + Create New.

Below are the shift rows: each row selects a shift, a time slot (from — to), a Priority number, and checks the days of the week the shift applies to. Click + Add Shift to add a row.

The Priority number determines which shift is suggested first when multiple shifts are open at the same time. A smaller number means higher priority.

Rotating crews

The Crews tab is designed for factory and hospital models: staff are divided into crews, and the crews rotate through morning, afternoon, and night shifts on a fixed cycle.

1. Set a Name for the rotation schedule.
2. Define each crew: crew name, branch (required), departments and employees, job title. Click + Add Crew to add the next crew.
3. Set the Effective period — the start date and end date of the rotation schedule.
4. In the Shift Plan table, each row is a shift; the columns Day 1, Day 2… make up the rotation cycle. Click + Add Shift Row to add a shift.
5. Click Create New.

If the form shows "Select a shift that has no active time frame and has an applicable scope matching the crews", it means the shift template you selected has a scope that doesn't include the crew's staff. Go back to the shift template (article B7-02), expand the branch or department scope, and try again.
