From what your article, from 1300 workers, 6 requested a change, and 2 were granted. May be I missed something in math class, but that does not qualify as a phenomenon, just a load of unverified rumours. Also, when you say "Many of the younger generation at the port are relatives of veteran workers; the port has the highest nepotism rate of any government company." don't you think this kind of accusation has to be backed by more than the observation that "many" (how many exactly?) are relatives to workers. In a small place like Ashdod, the biggest employer is bound to have many related workers. I'd be interested in statistics, not empty rhetoric. What do they teach at journalism classes?
