Worker

A "worker" is defined as a trick that is particularly well suited for use in everyday, "real-world," often challenging performing conditions - e.g., background noise, ambient (as opposed to directed) lighting, lots of distractions. In other words, a trick the magician can always rely on to get and/or hold his audience. They are usually quick, to the point, commercial, visual, and come about via a method that is, if not self-working, at least anxiety free. Examples of this would be a standard sponge balls routine or any basic Ambitious Card effect.

The term was popularized by Michael Close with his Workers series.
