Final answer:
The statement that public-sector supervisors and lower to midlevel managers have the right to engage in collective bargaining in more than a dozen states is true, as these rights vary by state and have been exemplified by events in Wisconsin.
Step-by-step explanation:
Public-sector supervisors and other lower to midlevel managers have the right to engage in collective bargaining in more than a dozen states. The statement provided is true. Collective bargaining rights for public sector employees vary significantly from state to state, but there are indeed more than a dozen states where such rights are recognized and protected. An example of an attempt to restrict these rights is the case in Wisconsin, where Governor Scott Walker proposed a bill that aimed to reduce the collective bargaining abilities of unions. While faculty members at the state college system were not unionized, other staff, including teaching assistants and researchers, had previously engaged in collective bargaining to secure better working conditions.
