We utilize employee reviews from Glassdoor.com to investigate the role of target firm employees and their ratings and reviews in corporate mergers and acquisitions (M&A) activities. Our findings indicate that, for private targets, employee ratings positively influence merger outcomes, whereas the effect is reversed for publicly listed targets. Our evidence supports two channels to explain these effects: the information channel and the employee satisfaction channel. Additionally, we find that catering to the needs of socially responsible institutional investors represents another plausible channel. In subsequent analysis, we delve into employee sentiment towards M&A by parsing em- ployee comments using the keyword-based textual analysis and a Bidirectional Encoder Representations from Transformers (BERT) model. Our results show that target firm employee sentiment positively influences both the likelihood of M&A completion and the overall M&A outcomes.
