W2s have been mailed by Central Payroll Bureau and are available on the Payroll Online Service Center (POSC). 

It appears that you can view/print your W2 from Chrome but you may need to "enable popups" for the W2 window to display.  

Several payroll updates have been posted on the Human Resources website  to include how to read your 2018 W2 and how to request a duplicate W2.   The 2019 W4 is not currently available but the site will be updated as soon as we receive it.
