In general there are three ways to organise a market. First, there is the free market in which workers compete freely to be chosen and paid by employers or clients. Secondly, there is a bureaucratic market which is hierarchically organised and controlled. And thirdly, there is a professional market which is organised and controlled by the specialised occupations themselves. In free markets the common interest of all participants is in monetary price and gain.
Workers typically have little interest in the work they do or in the way they do it.
They do what is necessary to maximise income. Price and profit are the measures of success, with efficiency defined by the minimisation of price in the production of a particular good or service. Workers generally have little job security. Actions are more constrained in a bureaucratic labour market. The incentives and values are different.
