5 Chief Human Resource Officers in Government Contracting

5 Chief Human Resource Officers in Government Contracting

Emerging technologies and workplace innovations are sprouting in almost every industry. However, the human resources sector can only thrive when the delicate balance between humanity and technology is maintained, according to HR software maker Sympa.

Industry leader Jeanne Meister said HR practitioners must prepare to embrace a "blended workforce" of humans and robots. Gartner predicts that by 2021, 25 percent of workers will be using virtual employee assistants on a daily basis. Such technologies include the range of conversational robots used for all types of HR processes.

The Potomac Officers Club – a division of Executive Mosaic – features five HR industry leaders from several premier govcon companies.
