This is a good idea.  I can confirm that the behavior is reproduced on a new 
user after I change shells to zsh, logout, and log back in..  the solution is 
simple enough: just append `SHELL=/bin/bash` to the line calling parallel:

#!/bin/bash
word="$1"
export word


work() {
  tar zcf $word.tar.gz $word
}

export -f work
echo $word | SHELL=/bin/bash parallel work
