Tata Motors CV business HR head Rajesh Nair has called it quits after serving the CV maker for 28 years. Nair was leading business HR for commercial vehicles, sales and marketing, customer care, and spare parts verticals.

Nair had joined the firm as a management trainee in the international business division, has held several leadership positions that include managing Safari and Sumo brands, heading sales and service for the western region, among others, in his almost three decades stint.

He was also involved in launching the pre-owned car business for Tata Motors and has also led the utility vehicles business before joining the human resources (HR) vertical almost a decade ago.

Nair's exit comes at a time when the Mumbai-based CV manufacturer is witnessing many top-level exits. The latest to leave the firm were Pratap Bose and Julian Thomson, both from the design department. Last October, Sujan Roy who was heading International Business for Tata Motors, quit after a decade-long stint. Meanwhile, the company’s CEO Guenter Butschek will move out of his role by June 30. Guenter was supposed to be replaced by Marc Llistosella, the former Daimler veteran, but the firm announced in March this year that he won’t be joining.
