How much control should corporations have over the speech of their employees?

Most of us are aware that the emergence of social media platforms and their omnipresence in our lives have fractured public discourse and undermined the conditions of democratic deliberation. But we are only now beginning to grapple with the way corporations — having already decided to make “values” and “ethics” central in their self-presentation to consumers — have become increasingly susceptible to public pressure to deal harshly with employees who express controversial, distasteful or simply divisive opinions. As a result, limitations on the speech of employees are being tolerated that would rarely be accepted within a democratic society.
