Of course a person’s personal life status affects the way they do a job. Because it affects the way they view the world.
You know, something that came as a surprise to me: In Israel, a job candidate is expected to put on their resume their age, marital status and whether they have children and how many. Totally unacceptable practice in the States (illegal to request, I believe), but standard In the Holy Land.
Why? I think for the reason I mentioned above; whether being married is considered a benefit or detriment for a particular job, it is considered the potential employer’s right to know.
Politicians waive their right to privacy; we find out about every doctor’s appointment they have, and everything their kids do or don’t do. That is because the press has decided (and rightly so, in my opinion), that everything they do is related in some way to what they stand for and/or how well they are able to do their job.
If you don’t believe in what a politician stands for in their personal life, you are likely to find yourself disagreeing with their policies at some point down the line. Follow your instinct.
