Career counseling is a career development initiative in which career education is provided to workers by career counselors to help them appreciate their motivations, explain their objectives, commit to action, navigate career transitions, and learn how they can contribute to the organization's overall effectiveness. The fundamental aims of counseling are to foster behavioral improvement, support decision-making, facilitate the capacity of clients, develop coping skills and improve relationships. Employee performance is a major challenge in organizational management and the key goal of any business enterprise is to take steps to inspire workers to deliver and achieve organizational competitiveness.
