For years, companies have touted that their employees are their greatest assets. But when it came to investment, these same companies invested in technology.
The companies purchased better lighting, invested in better machines (steam and electric conveyors), invested in better computers, better software, and better companies to implement the software.
These companies have continued to play the arms race game for the faster, better technology, outsourcing employees or just generally avoiding employee engagement. Investment more often than not goes to technology, not to people.
