Earned Income

Earned income is income derived from your job. It is linear in nature. You work for an hour and get paid only one time for that one hour's work, and that's it. Your income stops when you stop working. Unlike passive income, earned income or linear income requires that you work for your money. You are basically exchanging your time and effort for money. You get paid when you work. The moment you stop working, you don't get paid.
Usually to keep receiving earned income, one must still be "active" within the company or organization. Should they leave or break "policy", you can expect to stop receiving any further earned money. Replacing the mailbox money with a final termination letter and ceasing any more paychecks as the earned income comes to an end.
