Everyone is abusing everything. We've seen time and time again companies abusing employees with hard work, long schedules, unsafe environments and skimping on safety, which is why we have laws for safe working environments now. Sometimes work is physically hard, and the effect of that type of work usually doesn't show until you've done it for a longer time. So not only should you get money for the time and effort you…
That's not so much an effect of years of hard work as it is that as you get older your capacity for hard work declines. Also we already have government pensions. So why should a company have to provide them? The economic effect of this is that workers have to wait years for some of their pay instead of getting it right now.
I have known plenty of young guys in the UK who went on these fly in fly out jobs on gas or oil platforms in Australia, as it's a relatively uncomplicated way to get a well paid job (the only good thing about it) due to easy access to Australia, being commonwealth etc. Some of them turned into literal cripples within 2-3 years, others half cripples requiring re education or placement in a less physically demanding job. It's not the same doing this once for a weekend and then classify it as "not so hard" and go out there, work in 100 deg heat or sub freezing temperatures every day, rain, wind etc. It grinds down a body slowly.
