When Upper Responsibilities at a position worked permanently Increase ( being in charge of others, handling the Daily Cash reports,Hiring; MGR Duties--list could go on)
The Employee Get's a certain fair percentage increase in his/her take home pay based on the amount increase of responsibilities said employee is required to do.
