Call centers that handle requests for food stamps, Medicaid and other public benefits are understaffed. Nebraska's Child and Family Services Director Thomas Pristow told a legislative panel that staffing at Nebraska's four customer centers has not kept pace with the number of programs now handled by its employees. The call centers have received mixed reviews since the program was launched in 2010. Call times have trended downward, but some users still complain about long waits and mix-ups which caused them to lose their benefits. A new law requires the state to offer face-to-face services as well as the call centers. Lawmakers have said they'll likely push for more changes next year.
