+Get out of office
+-----------------
+
+* `GET /people/2/out_of_office.json` will return the out of office status for the person with the given ID.
+
+When out of office is not enabled, `start_date` and `end_date` will be `null`.
+
+###### Example JSON Response
+<!-- START GET /people/2/out_of_office.json -->
+```json
+{
+  "person": {
+    "id": 1049715914,
+    "name": "David Heinemeier Hansson"
+  },
+  "enabled": true,
+  "ongoing": true,

+
+
+Enable out of office
+--------------------
+
+* `PUT /people/2/out_of_office.json` will enable or update out of office for the person with the given ID.
+
+Admins on accounts with a Pro Pack can enable out of office on behalf of other people. Otherwise, you can only manage your own out of office.

+
+
+Disable out of office
+---------------------
+
+* `DELETE /people/2/out_of_office.json` will disable out of office for the person with the given ID.
+
+Admins on accounts with a Pro Pack can disable out of office on behalf of other people. Otherwise, you can only manage your own out of office.
+
+This endpoint will return `204 No Content` if the disable was a success. Disabling when out of office is already off will also return `204 No Content`.
