I've seen a lot of people in my own network who work at U.S. tech companies share this as an example of what companies should be doing. A lot of contrasting takes about how U.S. companies are laying people off while MB is handing out higher than expected bonuses.
Meanwhile, I know for a fact that a lot of the people sharing this are getting paid significantly more than these employees and also have bonus plans that pay out several multiples higher than the highest MB payout (7300EUR) even in a bad year.
Maybe this is an example of managing expectations. Mercedes-Benz paying four-figure bonuses to employees is noteworthy largely because they're paying more than expected. Meanwhile, I see people who earn significantly more being unhappy because their compensation was less than some number they expected.
Interesting lesson in how expectations are relative, not absolute.
