It gives us immense pleasure to present the book "Psychology of Human Behavior at the Workplace" to the third-year Commerce students of Mumbai University. While there are many books on this subject available in English, students studying through the Marathi medium often face challenges as books in their medium are not easily accessible in the market. To address this, we have made an effort to elaborate on all the concepts in this textbook in Marathi, which we hope will help alleviate the study difficulties faced by students. Therefore, it is with great joy that we present this book to students and discerning readers alike.
