We examine the potential for management-worker alliances when employees have substantial voting rights, and how such alliances affect the balance of power between managers and shareholders. We find that substantial employee voting rights exacerbate the manager-shareholder conflicts. Specifically, they entrench incumbent managers and allow them to pursue value-destroying acquisitions by undercutting the disciplinary influence of the corporate control market. Importantly, employee support for managers is conditional on favorable treatment of employees. Our findings are consistent with Pagano and Volpin’s theory of worker-management alliances and highlight the potential risks associated with large employee voting power.

Boards are crucial to shareholder wealth. Yet little is known about how shareholder oversight affects director incentives. Using exogenous shocks to institutional investor portfolios, we find that institutional investor distraction weakens board oversight. Distracted institutions are less likely to discipline ineffective directors with negative votes. Consequently, independent directors face weaker monitoring incentives and exhibit poor board performance; ineffective independent directors are also more frequently appointed. Moreover, we find that the adverse effects of investor distraction on various corporate governance outcomes are stronger among firms with problematic directors. Our findings suggest that institutional investor monitoring creates important director incentives to monitor.
