I don't know of any job where people didn't routinely get healthcare where they do now.
What I do know is that these days you'd be very hard pressed to find a job that pays less than "what a skilled tradesman makes at their first job that's better than entry level" that doesn't also cap you at 30hr whereas that wasn't the case before. So now everyone who had a poorly paid job before now has two of them.
Accountants, administrative assistants, maintenance people, custodians, delivery drivers, CNAs, etc, etc, have had their hours cut to avoid paying benefits.
I too would be interested in numbers. If there is any improvement it seems to be confined to some industry I am completely unaware of.
