"I Quit" is a phrase used to formally announce the voluntary termination of one's employment. It signifies the end of a professional relationship between an employee and their employer. This declaration is typically communicated verbally and followed by a written resignation letter outlining the employee's last day of work and, sometimes, a brief explanation for their departure. Leaving a job can be driven by various factors, including seeking better opportunities, pursuing personal goals, or addressing dissatisfaction with the current work environment.
