How does the FA know to complain without a legality checker? They have to go through the work of parsing the legalese and calculating time zone differences etc.

How does the FA know to complain without a legality checker? They have to go through the work of parsing the legalese and calculating time zone differences etc. And if they did complain, the airline says "Sorry, here's a freebie for your trouble" (worth 0.01% of the fine) Compare that to every FA knowing every single time there's a breach, being able to compare notes etc.
