Aliases are meant for interactive use and are ignored for scripts. This is because aliases are often used to override commands, i.e. aliasing "rm" to "rm -i" for root to make it extra-paranoid. But you wouldn't want automatic things to be run with -i.

If you want something a script can use, how about a function?

jh() {
        cd "/usr/bin"

These work fine in both scripts and logins.
