I did an apprenticeship in engineering back in the 90's and the abuse was pretty relentless for the full four years of my training. Most of it I found quite funny and laughed along with them but the other apprentice bit back and got it twice as bad. I soon realised you just had to go with it.
None of it would be allowed these days but on the other side, ignoring the abuse, the standard of mentoring was higher, apprenticeships were twice as long and you were expected to do the job and not just used as cheap labour.
It all went wrong when HR departments became a thing.
