rate Under UK law, piece workers must be paid in either at least the minimum wage for every hour worked or on the basis of a ‘fair rate’ for each task or piece of work they do. Output work can only be used in limited situations when the employer doesn't know which hours the worker does (e.g. some home workers). If an employer sets the working hours and the workers have to clock in and out, this counts as time work, not as output work. The fair rate is the amount that allows an average worker to be paid the minimum wage per hour if they work at an average rate. This must be calculated in a set way, a control trial is run to determine the average items produced by equivalent workers, this is divided by 1.2 to reach the agreed average figure, and the fair rate is set to ensure each worker achieves the minimum wage. There are several software programs that determine the time that a trained operator should take to perform an operation. MODSEW(TM) https://byte-ss.com/modsew/ is such a program, partially based on the motions that an operator is required to make to complete a task. In a service setting, the output of piece work can be measured by the number of operations completed, as when a telemarketer is paid by the number of calls made or completed, regardless of the outcome of the calls (pay for only certain positive outcomes is more likely to be called a sales commission or incentive pay). Crowdsourcing systems such as Mechanical Turk involve minute information-processing tasks (such as identifying photos or recognizing signatures) for which workers are compensated on a per-task basis. History Guild system As a term and as a common form of labor, 'piece work' had its origins in the guild system of work during the Commercial Revolution and before the Industrial Revolution. Since the phrase 'piece work' first appears in writing around the year 1549, it is likely that at about this time, the master craftsmen of the guild system began to assign their apprentices work on pieces which could be performed at home, rather than within the master's workshop. In the British factory system, workers mass-produced parts from a fixed design as part of a division of labor, but did not have the advantage of machine tools or metalworking jigs.
