I have been LR‘ed within the last 12 month.
You will lose access to most of the tools within 24 hours (and as well building) - except Webex, E-Mail, Workday and Stock-Account. Manager asks you to put an OoO mailer. After that call/meeting with your manager you will receive an e-mail from HR with all instructions incl. severance offering. You must leave inmediately any Cisco facility.
You will have 5 workdays time to accept or decline the severance agreement. Be aware that all your activities on your Cisco related devices are being monitored since a couple of days before your LR date and Cisco IT will continue to monitor it till you bring your devices back. Dont risk your severance, so be careful what kind of data you move to an external device or cloud storage.
On your last official day your Webex and Email account will be decomissioned. This is also the last they to bring back any gear like your laptop.
