Narrative:

The adjacent center controller descended aircraft X inside my airspace from 36;000 feet to 35;000 feet without getting control for an altitude change with our sectors. It is a requirement to get control for altitude changes in another controller's airspace. When this was brought up to the operations manager he said that this was not a problem.
