PAC Training

"PAC" is the acronym that stands for People @ Columbia which is the Human Resources system that integrates and processes all Human Resources, Benefits and Payroll transactions for Columbia University.

Employees – Faculty and Staff use PAC to view (and edit some) personal data, view compensation data, and submit time and absence data (once your department is enrolled).

Managers – Department managers view job and personal data for employees in their departments via MSS, generate reports, submit and approve transactions (per security role and access granted).  Reporting managers can view Talent Summaries for their direct reports and approve timesheets and absences (once your department begins using PAC for Time and Absence).

Initiators/Approvers/Central Administration – PAC Transactors, the Human Resources Processing Center (HRPC), HR Client Managers and Payroll perform various human resource actions related to hiring, pay processing, position and other data changes and processes including hire/rehire, additional compensation, and labor accounting transactions.

To access PAC, log in to myColumbia, enter your UNI and password and then confirm your access with multi-factor authentication (DUO).  For Managers and Transactors, PAC is accessed through the HR Manager Resources tab on myColumbia, then click "Go to PAC".
