Choice between A13 Z and E13 for a post-doc position in Germany I received a post-doc offer in physics from a German University. The position has a fixed three-year term, which might be extended up to three more years. The original position description says that this is the A13 Z position, Akademischer Rat auf Zeit. It corresponds to a Beamter, or civil servant position. Since I am a foreigner, the inviting professor is asking, whether it would be OK for me to switch it to E13 instead (researcher), since my profile for the position in this case is not needed to be checked by the federal government and the documents would be prepared much faster and easier for the inviting University. The salary would then be increased, to match those of A13 (let's assume the same net amount).

What are disadvantages and benefits of E13 compared A13 if one ignores the difference in the salary scale?

Which one is considered better in a long term?

Some more information on the personal situation:


Let's assume I'd like to stay in Germany afterwards.
I'm going to marry before starting the position. My partner has two children from the previous marriage.
I am not a citizen of the EU or the Schengen group.
A E13 position may have a little shorter working hours per week, for eaxample in North Rhine-Westphalia you have to work 39 hrs 50 min/week as "Angestellter" (E13) and 41 hrs/week as Beamter (A13). At least until you are 55 years old, as the working hours for Beamte get gradually reduced as you grow older. But I guess this would not apply to a post-doc position as academic work groups usually do not record the time of their scientist (this means, they often work longer hours without recompensation). 

As posted by Roland in his comment above, a Beamter has to get a private health care plan which can be expensive, depending on your age and health status, but as the state pays approximately half of your health care bills, the conditions Beamte get by the private health care companies are much more favourable in comparison to the ones offered to "regular" clients and in the end a Beamter has a higher net salary.

A Beamter has furthermore to pass a health test and perform a vow on the German Grundgesetz (constitution) and the German laws and is not allowed to go on strike. In case of permanent positions, the pensions for Beamte are significantly higher than the pensions for Angestellte. So if you are planning (or hoping) for a permanent position I think a position as Beamter might be more beneficial.

Your family status is also relevant for your salary as Beamter, this means, if you are married with children you will get a higher salary.
