What is wrong with hand holding? If someone never outgrows it, they may meet a lower salary for being inefficient. If someone succeeds without it, it doesn't happen. If someone needs it and doesn't get it, we spend twice as long cleaning up mistakes. In any case, handholding itself is never the problem, and avoiding it just masks more serious problems while regarding communication and relationship building.
The office is not the place for chest thumping dominance displays and contests of will.
