In California, where Luckey was employed by Facebook, it is generally illegal. I think this article is a reasonable summary of the California specific law: "Can I fire the Trump supporter who reports to me?" In California, the answer is clear — the law expressly prohibits employers from forbidding an employee from participating in politics, or controlling or directing an employee’s political activities or affiliations. Employers are also barred from firing or threatening to fire an employee in order to coerce him or her into any particular course of political activity. (California Labor Code Sections 1101 & 1102.) These provisions encompass and protect more than simply supporting a particular candidate or party. The California Supreme Court has decided the term “political activities” includes all activities that may indicate support for a particular candidate or a political cause. This broad definition of “political activities” protects California employees from discrimination based not only on which candidate the employee supports, but also on support for or involvement in the many social and political movements of today’s political landscape. Employees may not be fired or otherwise disciplined for participating in a climate march or attending an Ann Coulter speech; nor for going to a “Black Lives Matter” protest or supporting a border wall between the United States and Mexico; nor for countless opinions and activities in between. https://www.bizjournals.com/sanjose/news/2017/05/16/can-i-fire-the-trump-supporter-who-reports-to-me.html https://www.bizjournals.com/sanjose/news/2017/05/16/can-i-fi...
