    As a former employee I feel my personal information has been breached. Employees received letters stating that there system was hacked several months ago and certain or all employees personal info my have been taken. Cornerstone stated that they were monitoring the situation closely and then this happens. I myself am concerned. Maybe I should take legal action against them.

    Will employees receive any compensation for lost time, no fault of there own.

    Bill Baggins:

    This is thier 3rd cyber incident in the past 1.5 years. 2 email hacks and now the ransomware. Perhaps a class action seems appropriate.
