With the rapid advancement in technology and increased competition between corporations, Mergers and Acquisitions (M&A) become the immediate and wisest choice to get into new markets. This approach is employed by corporations with the intention to extend their business into a new domain and overcome an unrealizable state. Banks being the strong foundation of our economy, are constantly encouraged to merge to expand globally which will benefit the country economically. Currently, the Indian banking industry is considered to be growing rapidly altering itself into a dynamic industry. This sector has witnessed a new dimension through mergers and acquisitions enabling banks to attain a high ranking, giving huge recognition to the shareholders. The SBI Merger with its associates on April 1, 2017, was one such example. The foremost challenge for the management is regarding the human resource of the Organization. It is very important to understand the people-related issues in connection with the merger. This study aims to throw light on the employee perception on factors affecting job satisfaction level, post-merger. The research methodology is descriptive in nature and purely dependent on secondary sources such as books, e-books, journals, etc. The study recommends having a high degree of integration as the banks experience differences in culture due to the merger.
