I'm guessing you are using an inbound action for this? You will have to script it. If it's always in this format, you can do something like this:
var subject = email.subject;
var arr = [];
subject = subject.substring(16); //Removes the "Termination for " beginning string
var commalocation = subject.indexOf(',');
var name = subject.substring(0, commalocation); //The name is the resulting string up to the comma
subject = subject.substring(commalocation + 1).trim();
arr = subject.split(' ');
var id = arr[0]; //The first part of the resulting string is the ID
var date = arr[1].substring(1, arr[1].length - 1); //The second part of the resulting string is the date in parentheses
