After I clean the fine china to the satisfaction of my employer I intend to throw them in the dumpster.
Why would you throw those expensive dishes out?
I don't like the homeowner, who is my employer.
It's not uncommon to have issues with one's employer, but throwing away the china is wrong, as you shouldn't destroy the property of others. You could face legal consequences and/or lose your job.
I'll do it at night.
It's understandable to be frustrated if your employer is picky but that doesn't mean you should damage their property. Can you imagine how you would feel is someone did that to something you treasured?
