In the days following the fatal shooting of conservative activist Charlie Kirk, numerous workers have been fired for their comments on his death, among them MSNBC political analyst Matthew Dowd.

Several conservative activists have sought to identify social media users whose posts about Kirk they viewed as offensive or celebratory, targeting everyone from journalists to teachers.

It's far from the first time workers have lost their jobs over things they say publicly — including in social media posts. But the speed at which the firings have been happening raises questions about worker rights versus employer rights.

In the U.S., laws can vary across states, but overall, there’s very little legal protections for employees who are punished for speech made both in and out of private workplaces.
