+============================================
+Make work centers unavailable using Time Off
+============================================
+
+In Odoo, *work centers* are used to carry out manufacturing operations at specific locations.
+However, if a work center cannot be used for some reason, work orders begin to pile up at the work
+center until it is operational again.
+
+As a result, it is necessary to make the work center unavailable in Odoo so that the platform routes
+new work orders to alternative work centers that are operational. Using Odoo *Time Off*, it is
+possible to designate a work center as being unavailable for a set period of time. Doing so ensures
+that manufacturing operations can continue until the impacted work center is available again.
+
+Configuration
+=============
+
+Before a work center can be designated as unavailable, the Odoo platform must be properly
+configured. First, it is necessary to enable :ref:`developer mode <developer-mode>`. This allows the
+:guilabel:`Time Off` smart button to appear on each work center's :guilabel:`Working Hours` pop-up
+window.
+
+Enable developer mode by going to :menuselection:`Settings`, scrolling to the bottom of the page,
+and clicking :guilabel:`Activate the developer mode` under the :guilabel:`Developer Tools` heading.

+
+Next, install the *Time Off* app. This is the app used for assigning time off to all resources
+within Odoo, including employees and work centers. Navigate to :menuselection:`Apps`, then type
+`Time Off` in the :guilabel:`Search...` bar. The card for the :guilabel:`Time Off` module should be
+the only one that appears on the page. Click the green :guilabel:`Install` button on the card to
+install the app.
+

+
+The last step is to properly configure work centers. For this workflow, it is necessary to have at
+least two work centers: one that is made unavailable and a second that receives the work orders that
+the other cannot accept. If no second work center is configured, Odoo cannot route work orders away
+from the unavailable work center and they will pile up in its queue.
+
+To create a work center, navigate to :menuselection:`Manufacturing --> Configuration --> Work
+Centers --> Create`.
+
+Make sure that both work centers have the same equipment listed under the :guilabel:`Equipment` tab.
+This ensures that operations carried out at one work center can also be performed at the other.
+

+
+For the work center that will be made unavailable, select the second work center on the
+:guilabel:`Alternative Workcenters` drop-down menu. Now, Odoo knows to send work orders to the
+second work center when the first is unavailable for any reason.

+
+Add time off for a work center
+==============================
+
+With configuration completed, time off can now be assigned to the work center that will be made
+unavailable. Begin by navigating to :menuselection:`Manufacturing --> Configuration --> Work
+Centers` and selecting the affected work center. Click :guilabel:`Edit`, and then the :guilabel:`↗
+(external link)` button next to the :guilabel:`Working Hours` drop-down menu.
+
+.. image:: work_center_time_off/working-hours-button.png
+   :align: center
+   :alt: The Working Hours "External link" button on the work center form.
+
+A pop-up appears, titled :guilabel:`Open: Working Hours`. The standard working hours for the work
+center are listed here, along with various other details about it. Since developer mode was enabled,
+there is a :guilabel:`Time Off` button in the top right of the pop-up. Click it to be taken to the
+:guilabel:`Resource Time Off` page.
+
+.. image:: work_center_time_off/time-off-button.png
+   :align: center
+   :alt: The Time Off button on the Working Hours pop-up.
+
+On this page, click :guilabel:`Create` to configure a new time-off entry. On the time-off form, note
+the :guilabel:`Reason` for the work center closure (broken, maintenance, etc.), select the affected
+work center as the :guilabel:`Resource`, and choose a :guilabel:`Start Date` and :guilabel:`End
+Date` to specify the period during which the work center will be unavailable. Click :guilabel:`Save`
+and the time off for the work center is logged in Odoo.

+
+Route orders to an alternative work center
+==========================================
+
+Once a work center is within its specified time-off period, work orders sent to it can be
+automatically routed to an alternative work center using the :guilabel:`Plan` button.
+
+Begin by creating a new manufacturing order by selecting :menuselection:`Operations -->
+Manufacturing Orders --> Create`. On the manufacturing order form, specify a :guilabel:`Product`
+that uses the unavailable work center for one of its operations. Click :guilabel:`Confirm` to
+confirm the work order.
+
+On the confirmed work order, select the :guilabel:`Work Orders` tab. By default, the unavailable
+work center is specified in the :guilabel:`Work Center` column. There is also a green
+:guilabel:`Plan` button on the top left of the page.
+
+.. image:: work_center_time_off/mo-plan-button.png
+   :align: center
+   :alt: The Plan button on a manufacturing order.
+
+Click :guilabel:`Plan` and the work center listed under the :guilabel:`Work Orders` tab is
+automatically changed to the alternative work center.
+
+.. image:: work_center_time_off/work-center-planning.png
+   :align: center
+   :alt: The selected work center updates automatically after clicking the Plan button.
+
+Once the time-off period for the unavailable work center ends, Odoo recognizes that the work center
+is available again. At this point, clicking the :guilabel:`Plan` button does not route work orders
+to an alternative work center unless the first one is at capacity.
