If an individual is not interested in doing people management, it is an indication of his strong passion for technology and product. In a technologically driven industry scenario, such people are actually more efficient and result-oriented. They do not want to waste their time arranging special meetings for 'motivating' people. They just resolve the technical problems of their colleagues 'on the fly'. Such people are normally very reasonable and help their colleagues in a friendly manner.
The only problem is that they do not like to make a show of these additional activities they perform.
Secondly, a person who is technically very strong does not like to handle the mobilization of people, demobilization of people, ensure that the visa of some colleagues is expiring, or air ticket of some colleagues is not confirmed, etc.
So if a team lead hates people management, there is no problem, but the only thing necessary is to ensure that he is a well-behaved gentleman and treats his colleagues reasonably.
