One thing you could do immediately is revise some of the Fair Labor Standards Act (which governs overtime and exemption from overtime laws) to limit/eliminate certain classes of what are currently "exempt" employees. By exempt, these employees can be made to work heinous overtime hours for no additional pay. It's great for employers but not so great for overworked employees. Would probably also force a fair number of larger companies to hire as well, since they'd otherwise be forced to pay time-and-a-half etc.
Would need to study the degree to which this would hurt smaller businesses, however, who might not be able to afford the hit. I know for a fact, however, that large corporations in down economies are abuisng the crap out of this to squeeze their workforce to hell and gone.
