You introduce the dinosaurs to the concept of collective bargaining, and, just as importantly, the concept of a strike. As they walk off their dinosaur jobs and labor grinds to a stop, the richest owners of the dino factories buckle and agree to come to terms. Under your guidance the dinos win better working conditions, shorter hours, and higher wages. Well, not like literally shorter hours as in 55 minutes per hour or something. "Fewer hours" really. Fewer hours in a work week. Anyways, you become a legendary labor leader here before heading back to your human world that’s luckily not at all like the dino one was and definitely has no worker's rights issues.
