I present a novel measure of partisan alignment between firms and employees. This measure is constructed using data matching 1,691,790 US federal campaign contribution filings of 85,109 individuals to the donations of 874 Political Action Committees (PACs) of publicly listed US companies between 2003 and 2016. The alignment measure shows that employee and employer contributions are highly correlated. Furthermore, firm- and occupation-level factors are significantly associated with firm–employee alignment. Uniquely, these new data can be easily linked to external data on industries, firms, and occupations and consequently allow for in-depth analysis of precisely how companies can influence employees’ politics.
