Job title for people who do all of the hard work but get none of the credit.
Twenty years from now I'll still be a worker bee.
A "worker bee" is a prostitute; a woman who engages in sexual acts in exchange for money or other items of value. Especially one in a group of prostitutes.
While taking a cab from the Las Vegas airport to your hotel you might say to your fellow passenger regarding the sleeze talent en route, "Looks like the worker bees are out in force tonight".
