Employee Name Change

McMaster is committed to fostering belonging and respect for individual identities.  

Starting October 6, 2025, employees can update their chosen/preferred first name directly in Mosaic through Employee Self Service (ESS).  

This page explains how to manage your chosen/preferred first name, full legal name, and publishing name, and how each will appear in Microsoft 365 and other university systems, as seen by your colleagues and the broader community. 

Chosen/Preferred Name 

Your chosen/preferred name is the first name you choose or prefer to be addressed by. It may differ from your legal name and reflects how you wish to be addressed in day-to-day university communications with colleagues through Microsoft applications (outlook, teams and more). 

Legal Name 

Your legal name is your name that is listed on your valid government ID. This could include passport, driver’s license and other forms of identification (which include your name, date of birth, photo and signature). 

Your legal first and last name will remain in Mosaic, even if you update your chosen/preferred name, as it’s required for government reporting, payroll, benefits, and retirement plans administration purposes.
