Why not change "mainWork" such, that it accepts a Class ref directly,
rather than the canonical name?
Maybe even simpler would be to have it accept a SQL ref and just pass

You might want to add "protected", so that derived classes even in
other packages can still call it. "protected" is more permissive than
default access.
