Store the career level of employees to make reporting simpler

[nikslor]

For reports, I often need to know how many team members had a certain career level (e.g. "Junior System Engineer" or "Head of Operations", ... ) on a specific date (often January 1st or December 31st, but sometimes also a random date).

To create such reports, I currently use our (internal) employee spreadsheet which also gets archived and then do some filter foo to get the needed information. This is cumbersome manual work that leads to errors. To make my life simpler, I propose the following feature.

We already store contract related things such as the workload (Arbeitspensum) per user in timed and even have this information assigned to a start- and an end-date. Please add another "field" so we can also store the career level - this also needs a start- and an end-date, and it must be independent of the workload start- and end-date.

Definition of done:

• our backoffice team can set the career level per user and assign a start- and an end-date (no end date means: it's the current career level) in the GUI
• I can get a simple report (ods/xlsx or cvs) with all employee names, their career level and their workload of a certain date from timed
