Social Security beneficiaries could face longer wait times for service next year unless Congress agrees to the White House budget office’s request to increase funding for the Social Security Administration (SSA), the administration that runs the program is warning.

House Republicans balked at increasing funding for the SSA in the continuing resolution passed in September, which forced the agency to implement a hiring freeze last month.

As a result, the SSA will soon reach a 50-year low in staffing despite having to provide service to a record number of beneficiaries, which means customers will experience longer wait times on the phone or online when trying to resolve problems.
