Over the last several years, customer demand has become less predictable than in years past, creating new challenges in the workplace. When demand quickly increases, companies typically respond by hiring additional workers or relying on existing employees to pick up the additional workload. As demand decreases, some businesses are forced to lay off their recent hires. The delicate balancing act of adjusting employee levels to meet customer demand causes friction in the workplace and can negatively affect productivity and overall employee morale. Thus, companies need to find the most efficient and effective way to meet these changing levels of customer demand.
