Meaning of HARDENING in English
Used to describe the resulting condition of a worker when his boss gives him to much work to do. The body just stiffens into a rigor mortis state and the worker becomes unable to function. From a Dilbert cartoon by Scott Adams Example: B. Isok, I have another project for you. (Isok then stiffens like a board, arms spread wide.) B. Isok, are you hardening?
