What corrective labour is
Corrective labour is the form of administrative penalty that involves neither a change of workplace nor deprivation of liberty. Under Article 31 of the Administrative Offences Code of Georgia, corrective labour is applied for a period of up to six months, and the person who committed the administrative offence must serve it at their permanent place of work. Up to twenty per cent is deducted from their wage in favour of the State. In other words, you keep working where you already work, and the penalty is served through wage deductions and through the recorded time actually worked. That structure is what makes the arithmetic of the sentence, rather than the fact of it, the thing most often disputed.
One practical consequence follows directly from it: the penalty is measured in two units at the same time — the calendar period fixed by the court, and the working days actually worked and recorded at your place of work. Almost every question people have about corrective labour comes out of the gap between those two units: when the penalty ends, what happens during a period of illness, and what becomes of the term when a person is temporarily not working at all.
