So, we assume that such was true in the time that EGW wrote.
But, is it possible that today some labor unions might exist for which what EGW stated would not be true?
As an example, I can show you quotations that suggest that labor unions hindered a SDA from being free from working on Sabbath. Yet, this labor union clearly seems to support the idea that this person should be freed from working on Sabbath.
Context is important. Is it possible that there may be labor unions today that do not represent the problems that EGW mentioned in' her comments?
We can look back through history and see where labor unions have been involved in violence, to include murder. We can see where labor unions called upon their members to strike.
What if we found a labor union that in its entire history had never called for its members to strike and had never been involved in violence?
By the way such labor unions do exist.
