PAC Time & Absence Management

Phased Rollout based on Implementation Schedule

Absence Management is a module within the People @ Columbia (PAC) application that allows employees to see their current balances for vacation, sick and personal days at the end of each pay period.

Time Reporting is a module that allows employees to enter their timesheets electronically directly into PAC.

Employees will view absence balances and enter their time off through my.Columbia Employee Self-Service. The information stored in the system will be the authoritative source for balances and allow the University to have an accurate estimate for these paid time off categories. Time Reporters will also access their timesheets through my.Columbia.

Please refer to the links on the right side of this page for training documents.

For questions about the various University leave policies, please refer to the Time Off Work policies, available in the Policy Library.

Since the Absence Management and Time Reporting modules are within the PAC application, they are only accessible when PAC is available. The PAC application is available daily except for the times listed below:

  • Monday – Saturday: 12:00 a.m. – 6:00 a.m.
  • Thursday: 5:00 p.m. – 7:00 p.m.

There may also be system downtime periodically throughout the year to accommodate required system maintenance.  

To ensure login security, employees will be prompted to log in using DUO, a multifactor authentication service. In addition, Columbia University requires that all users of the PAC application change their password every 90 days. This is a precaution to help protect the sensitive personal and payroll data of all faculty and staff.
