“Back to the salt mines”

“Back to the salt mines” means back to unexciting work, or “back to the daily grind.” It’s a comment often made after a weekend away from work.
 
“If he starts anything with me I’ll chase him back to the salt mines of Siberia” was cited in a newspaper comic strip in 1926. “Salt mines” often implies the salt mines of Siberia, such as those at Usolye-Sibirskoye. It’s not only hard work in a desolate place, but it’s also penal colony imprisonment. Later citations of “back to the salt mines” usually leave off “Siberia.” “Well, Gilly, it’s back to the mines for me”—leaving off “salt”—was cited in 1933.
