the s command will allow characters other than /

echo "this is old crap not pig's ears" | sed -e 's/old crap/new stuff/'
echo "this is old crap not pig's ears" | sed -e 's#old crap#new stuff#'
echo "this is old crap not pig's ears" | sed -e 's,old crap,new stuff,'

Therefore:

sed -e 's#/usr/test/working/##' < original > cleaner
