Work-to-rule and holidays, and police officers refusing to issue citations. Refusal to work overtime, travel on duty, or sign up to other tasks requiring employee assent are other manifestations of using work-to-rule as industrial action. It was described by Sir John Donaldson as a decision to "Give the rules a meaning which no reasonable man could give them and work to that." Sometimes the term "rule-book slowdown" is used in a slightly different sense than "work-to-rule": the former involves applying to-the-letter rules that are normally set aside or interpreted less literally to increase efficiency; the latter, refraining from activities which are
Work (thermodynamics) energy as heat because of its non-mechanical nature. Another important kind of work is isochoric work, that is to say work that involves no eventual overall change of volume of the system between the initial and the final states of the process. Examples are friction on the surface of the system as in Rumford's experiment; shaft work such as in Joule's experiments; and slow vibrational action on the system that leaves its eventual volume unchanged, but involves friction within the system. Isochoric work for a body in its own state of internal thermodynamic equilibrium is done only by the surroundings
