The push for chief mine inspectors to have eight years of experience was a positive change to labor laws because it helped ensure that the individuals responsible for overseeing mine safety had a sufficient level of experience and knowledge. This experience requirement helped to reduce the likelihood of accidents and injuries in the mines, which in turn helped to protect the lives and well-being of mine workers. By requiring a certain level of experience, the government was able to set a higher standard for mine safety and help prevent accidents that could have been caused by inexperienced or untrained personnel. Overall, this change was a positive step towards improving working conditions and protecting the rights of workers in the mining industry.
