For those wondering how a stay letter looks like, here's a what somebody ( @W10AUMB-vam ) pasted from the content of the PDF in another thread:
We are pleased to welcome you to Broadcom! As you know, Broadcom acquired CA, Inc. in a transaction that was
completed on November 5, 2018.
In the days ahead you will be receiving updates from IT, Payroll, Workplace Services, and other functions via email.
Please look for these updates, which will contain important information to help you with the integration.
In mid-December you will receive a personalized Welcome Letter that will detail your compensation components, title,
and reporting structure as an employee of Broadcom.
We are happy to have you part of the organization and look forward to the year ahead!
That's a "stay" letter or I'll eat my hat.
