Delegating isn’t dumping. If you hand off the boring part and keep the fun part, everyone notices.

People accept uneven work far better than they accept being used. Handing out only the tedious jobs while keeping the interesting ones tells everybody exactly where they stand, and nobody has to say it aloud for it to be understood. The work still gets done for a while, and then the willingness goes. The arithmetic fools no one.

Look at the last few things you handed off and check whether you kept the good parts. Give away one job you would have enjoyed, and take a dull one yourself. Put the worst task in a rotation that includes you.
