Boolean Value For Each Worksheet

I have a timecard spreadsheet which im working on, each employee is represented by a single worksheet in the workbook, and the worksheet is named after the employees name. New employees are added by filling in a form which dynamically creates the timecard based on a template. Im trying to impliment a 'Fire Employee' button which sits on each employees sheet and can be clicked to set an employees working status to false by changing a boolean variable called 'fired' to true.

Ive been looking around the forum but I cant figure out if i should be using public variables or where exactly i should be placing them, so that each employees 'fired' status is set to false when the worksheet is first created, but can be set to true when the 'Fire Employee' button is clicked, this must only set true for that specific employee, and not all employees. If your wondering why i need this, the employees work status will be used on other forms to toggle views etc so thats why a boolean approach is best (at least i think it is if its not to difficult to do)
