Little pressure from superiors (unless you put it on yourself), no short-time work, no site relocations combined with operational layoffs, secure development up to the target salary by "serving time", family allowance, total flexibility regarding family, high pension compared to the state pension, practically unfireable.
I wonder here whether this is an assessment based on hearsay or if you actually know in detail in a large number of cases and are certain enough to make such a statement. It probably comes, as almost always, from hearsay and such a sweeping judgment is gladly used to defame professional groups.
I know from my professional years several employment relationships and also the respective advantages and disadvantages; still, I would not presume to make a general judgment.
You find the same lazy bums in corporations like Siemens, Bosch or Daimler as in some government offices, among employees as well as among civil servants. But you also meet dedicated civil servants and employees. It is actually a shame that such defamations must be refuted, as nowadays everyone could know that it is not a question of profession, origin, or religion whether someone is lazy or stupid or diligent or intelligent; often an honest look in the mirror would also help.
Civil servants are lazy and get everything for free, employees earn less and are under pressure, and self-employed people are generally rich and can always arrange their work as they please... AND... my favorite phrase: "... they can deduct it from taxes."
A former boss used to say: "If someone is an idiot, he’s an idiot whether he is a civil servant, employee, or self-employed. He was right!
Unfortunately, experience values, not pub talk. My wife came from the private sector (law firm), earned almost half as much there, significantly more pressure, and had to accomplish much more than now. The good ones usually get their daily work done easily in 5 hours. Those who are committed then often carry many low performers through out of good will so the department does not completely sink. But she has given that up by now; it simply doesn’t pay off because (extra) performance is absolutely 0.0 appreciated and rewarded. So service according to regulations is done and the rest of the time is spent drinking coffee and chatting. I can't even blame her for that; I think this resignation is human. This is, in my opinion, the biggest problem with civil servitude.
I especially like to listen attentively when someone then says that naturally he himself (who else??) is always the one surrounded by laziness and incompetence, of course always the others are the sluggish coffee drinkers, without forgetting to hint at his own constant top performance, strictly according to the motto "I send my best man, I come myself."
My experience tells me, on the other hand, that where loud whining is heard, one should better look in the mirror oneself; surely your wife’s colleagues probably do not see her as this top-performance turbo as you see her or she sees herself; you can be sure that their judgment would differ greatly from yours and, of course, these colleagues will rather see themselves in this top position already occupied by your wife.
Ergo - such blanket judgments are complete nonsense and show little overview of the whole, sorry!
If it is so great to be a civil servant, why didn't one just become one or why doesn't one quit at 40 and become one? After all, you are so flexible, capable, and always the sole support of the company, so there is enough for a lousy civil servant job somewhere.
It is quite simple... it is usually the whining of the dissatisfied about their own situation, into which they have pushed themselves entirely alone (as adults fully responsible) and making full use of their freedom, and now they rant or once again naturally look for the blame with the others, the lazy ones, the overprivileged.
As a coach once said to a teammate who claimed he had run so much during the whole game: "That's true - ... running around pointlessly on the pitch ..."
Otherwise, I recommend the approach according to the well-known motto: "Love it, change it, or leave it" - and please don’t tell me such crap!
