Title of your thread has me wondering...He's a New Hire Demanding...
Tell him to be thankful that he has a job. Typically benefits at most company s. don't start until after the employees probationary period. ie 3 months. Have this new guy prove himself first before any further talk about benefits.
The title doesn't seem to go with the rest of the thread.
We never were told what, exactly, were the demands.
Everyone is different, but if I were a 'new hire' making demands, it would be because the employer needed me WAY more than I needed them. That would also mean I had other prospective employers willing to meet my demands, and if I didn't get my way, off I would go.
But....I wasn't a helper, nor was I about to do menial tasks and I certainly did not need any training from my employer for what I was doing. (Specialized electrical work)
So, with no further information, all we can give the OP is what he has to do to keep within the law, which equates to the bare minimum.
I have also found that minimum wage usually means minimum desire to work, capability and productivity. Not always, just usually.
