What kinds of jobs in the United States don't offer their employees health insurance?

As in, a health insurance plan is part of their pay deal etc. Just curious really.

non-skilled labor, child care, part time work, those kinds of things. The issue isn't really not being offered healthcare from your employer, it's not being able to afford the premiums and deductibles on a minimum wage salary. A worker can be offered insurance from their employer, but it may cost too much of their paycheck. So then it becomes a choice between food for dinner or healthcare
