Answer:
According to the Constitution, a justice of the Supreme Court shall hold their offices during good behavior.
Step-by-step explanation:
So long as a justice behaves well and according to the law and is not corrupt, they shall hold their place in the supreme court. Justices can be removed by impeachment, retirement, or resignation, but they cannot be "fired" from their jobs. If a justice is corrupt, actions can be taken to impeach them, much like in instances with presidents. Hope this helps :)
