That is not odds with philosophy adoption at all. In fact, nature of these (imagined) miners problems can make it harder to adopt philosophy that would make it harder to seek solutions to very real problems they have. If you endure pain with no display, your pain is taken less seriously after all and at some point, you need that doctor to understand it is real. And at other point you already need to stop working or fight for better conditions. Very real miners were very real dying and passive acceptance of that was not what bought changes.
But in case of tech people, stoically waiting is to your benefit as tech is generally higher status job. Moreover tech workers often time primary use stoicism to put expectations on other people rather then themselves.
Generally, if you are male, no one is going to look on you with much sympathy if you express that you are in pain. Pity and contempt are the more likely outcomes. Stoicism is a tool that helps it to be a little easier to suck it up and drive on and do your job.
You do get a doctor to have a look at your hand or back. You can get pain relief medication. Stoicism is not philosophy for people at breaking point nor thos with real problems that needs to be solved actively. You as tech worker think about how others looks at you and consider social status. Poor miner needs fix for back that is hurting enough to prevent him to fully perform which puts him at risk to be even poorer.
My poit is that civil rights nor security regulations nor anything like that happened because people were stoic.
Moreover, places with those sucky-destroy-you miner jobs tend to, well, not be stoic. They have host of social problems, alcoholism, drugs, physical fights etc. These people are not signing to stoicism as philosophy. They are drawning and reacting to that.
But in case of tech people, stoically waiting is to your benefit as tech is generally higher status job. Moreover tech workers often time primary use stoicism to put expectations on other people rather then themselves.
