Fixed Hours or Custom Shifts?

Atteny can run on each location's opening hours or on shifts you build per person. Here is how to pick, and what each choice changes.

For admins

Requires the Scheduling module to be turned on in Settings → Modules.

Atteny plans work in one of two ways: Custom Shifts, where you build shifts per person, or Fixed Hours, where everyone follows their location's opening hours. The choice applies to your whole company.

Only an admin can change the schedule mode. The page it is on exists only while the Scheduling module is switched on.
  1. 1

    Open the scheduling settings

    Open Settings and then Scheduling. The two modes are the two cards under Schedule Mode.

    The Schedule Mode card on the Scheduling settings page, showing the Fixed Hours and Custom Shifts choices, with Custom Shifts selected
  2. 2

    Pick a mode and save

    Select a card, then select Save at the top of the page. Save stores everything this page shows: the mode, the Breaks settings and, when that card is shown, the Availability settings.

Custom Shifts#

This is the mode a company starts in. Admins, and managers who are allowed to, build individual shifts for each person. See Building the week.

Fixed Hours#

Nobody builds shifts. The schedule is worked out from each location's opening hours every time someone looks at it, and nothing is stored.

  • Who gets hours. Every active person assigned to a location, whatever their role, gets one shift for each opening window of each open day there. Someone assigned to two locations gets both. A day that is closed, or has no saved hours, gives nobody a shift.
  • Where the hours come from. Open Locations, your location, then the Scheduling tab. The hours are in the Shifts card, under a Fixed Hours Active notice. In this mode the tab hides the settings for shift length, people needed, availability, shift swaps and open shifts.
  • Shifts cannot be changed. Adding, editing, cancelling or deleting a shift, copying a week, publishing drafts and Auto Schedule are all refused when you save. To change who is expected when, change the location's hours, or switch back to Custom Shifts.
  • Late or on time. A person's first clock-in of the day is measured against the opening it was for: one that starts within the next 30 minutes, otherwise the one it falls inside, otherwise the last one that had begun that day. With openings at 08:00 and 13:00, a clock-in at 12:50 is on time for 13:00, and one at 12:20 counts as late for 08:00. Coming back from a break is not measured again, even when the break runs past midnight, and a rejected clock-in is not measured.
  • No alerts for these hours. Late arrival or no-show and Missed or short break go by a shift somebody scheduled. Fixed Hours has none, so neither is sent. For the same reason the Schedule vs actual report is empty for weeks spent in Fixed Hours.
  • A shorter menu on the web. Under Schedules, the entries Shifts, Availability, Shift Swaps and Open Shifts are hidden.
  • On the phone. An employee's Schedule tab is marked Fixed Schedule and shows their own hours. On Manage Schedule, the buttons for adding, copying and auto-scheduling are hidden, and so is the draft switch. Shift Swaps can still be opened while its module is on: the screen explains that there is no individual shift to hand over.

Which one suits you#

Pick Fixed Hours when the same people work the same hours every week: an office, a clinic, a shop with settled hours. Pick Custom Shifts when who works when changes from week to week, as in most cafés, restaurants and retail.

Before you switch to Fixed Hours, save the opening hours of every location on its Scheduling tab: hours are worked out only for locations whose opening hours were saved. Switching deletes nothing. Shifts that began before the switch stay as they were, so past weeks, pay, timesheets and reports are still read against them. Shifts that begin after it are set aside while the company is in Fixed Hours: nobody sees them, and they are not used for late alerts, clocking in, leave or shift swaps. With Fixed Hours selected, the page tells you under the two modes how many shifts are set aside. When you switch back to Custom Shifts, the ones that are still ahead come back; the time the company spent in Fixed Hours stays as it was.

If the Scheduling module is off#

With the Scheduling module off, the schedule screens are gone in both modes: the web has no Schedules entry, and on the phone the Schedule tab gives way to Notifications. So people in a Fixed Hours company lose the page that lists their fixed hours. Clock-ins are then measured against each location's opening hours, in both modes. The page with the mode switch is gone until the module is on again: see Choose your features.
