**As** a resource manager
**I want to** track for each user in the system on what weekdays they work, how many hours per day they work, when they are not available
**so that** I can properly plan my resources.

**Acceptance criteria**

* Add new feature flag "User Begin of the insertionWorking Times"End of the insertion Begin of the deletion Availability"End of the deletion

* Add new global settings page for User availability

* Allow global enable/disable

* For every user in the system it is possible to track

* Working days

* How many hours per day they work.
We chose this over a weekly work time so we can properly overlay this with work packages

* An _availability factor_. We acknowledge that users will not always work 100% on project work. Daily business and other stuff happens. So we can specify this factor (i.e. user works 40hrs per week, availability factor of 80% --> 32hrs of resource availability)

* Vacation times and other unavailable days should be trackable. For privacy reasons, no more details than just unavailable days should be tracked (i.e. no differentiation between holidays and sick days)

* Calendar view similar to the global non-working days

* Global non-working days are shown in the personal availability calendar

* Global non-working days are considered when you calculate availability - This will fail rather quickly as soon as you have multi-country users

* There should be a setting, if those hours can be edited by users themselves, only with a certain role, or not at all

* The availability per user should be changeable by the API

* Availability times have a start date (and an implicit end date) to prepare for changes

* Modification should be handled by a new tab in the user edit page.


**Technical notes**

* Availability times should be logged like hourly rates. With a starting date. That will work properly with users switching from full to part time, etc

* Old availability records cannot be edited but new ones can be added.


**Permissions and visibility considerations**

* Users can always view their own times

* New global permissions

* "Manage own availability"  - this is added to the Standard global role

* TBD "View availability of other users" ?

* We might need to have this restricted to departments, groups, etc.

* "Manage availability of other users"


**Translation considerations**

**Out of scope**

* We do not want to become an HR system. So things like vacation requests, etc will not be implemented

* The UI to manage the data is a help for smaller customers. We expect the data to mostly be injected into our system by an external service (HR system, etc) via the API
