The industrial revolution was added to history books in the 17th century. Since then, more and more rules and regulations have been constituted for the hiring of labour and the remuneration of workers in an attempt to discover a satisfactory one that would be acceptable to the employer and adequate for the workers to suit a particular type of industry. One of the oldest methods in existence of remunerating workers is the "time work method," also referred to as "day work," "day rate," "time rate," etc. By this method, the worker is paid a stated sum per day of 8, 9, or more hours, or per week of 40–48 hours and upwards, in accordance with the custom prevailing in the particular industry. The general popularity of this system of remuneration may be attributed chiefly to its simplicity as regards the calculation of wages, etc. In modern practice, however, this method is modified by the introduction of various bonus schemes. In fact, the institution of schemes embracing a monetary incentive towards increased production has resulted in a considerable increase in production, with a consequent benefit to the employer and employee. Hence, this method is adopted by the maximum number of industries and is still going stronger and stronger. In the time-work method, the first essential is the ascertainment of the total time spent inside the factory, etc., for which the worker is entitled to draw wages. The three chief methods of recording workmen’s time are manual recording, the check or disc method, and the time recording clock method. The manual system is the oldest and is still in use, mostly in small industries. The disc method, which is superior to the manual system, is gradually falling into disuse. The time recording clock method is becoming more popular. The device used for recording a worker’s time is a time punching machine. The existing time punching machine has good scope for development and improvement, so a redesign of it is sure to receive a warm welcome.
