People died so you can have an 8 hour workday, and they organized in the workplace.
Many of the 'work standards' laws (including child labor laws) were actually enforcing standards and best-practices which originated from industry leaders. One example is how the mechanized textile manufacturers eliminated child labor (as it was unnecessary and uneconomical), then lobbied governments to ban child labor (probably to 'punish' their competitors). The 40-hour work week (largely) originated at various industry-leaders (notably including Ford, which was very efficient, and preferred energetic and loyal workers over tired and seasonal ones).

Similarly, the push for 8 hour workdays began with union support in the mid 1800s, 50+ years before Ford popularized it (and in fact it was due to this pressure that public sector employees had 8-hour workdays as early as 1869).
Individual states had banned child labor and passed 8-hour workday laws (due to union and public pressure) far before Ford or the Textile mills did so "voluntarily".
None of my employers limited work hours or work days or children at work because of political discourse in the office. Nor did historical companies from 3 generations ago when such laws were passed.
All of those laws were created because companies did NOT implement such limits.
