業 originally depicted a type of rack or stand used in music or ritual, later extended to mean work, profession, or performance. The modern form is highly stylized and its component breakdown is not straightforward.
The top 业 looks like a simplified workbench, the middle 䒑 like a pair of hands, and the bottom 未 like an unfinished task. Picture a craftsperson at a bench, hands busy with a work in progress: that's 業, your business or art.
For ギョウ, imagine a skilled performer named Gyo who turns every task into an art: Gyo -> ギョウ, and his performance is the heart of his business.
