As a matter of fact, online piecework and crowdsourcing are overlapping but distinguishable concepts, the difference being centred on the size of the tasks. To sum up, the contractual scheme allows the engagement of “a large, distributed, global labor pool of remote workers” to whom tasks can be commissioned (177). It can be said that online crowdsourcing is the most elusive segment of collaborative economy. To date, perhaps not surprisingly, there are no tailored regulations governing these workers. Being perhaps the most genuinely unprecedented segment of this phenomenon, it has not been captured by the legislator yet. The online labour market for professional activities is more sensitive to the intervention of the lawmaker – particularly in those areas where specific restrictions and charges set by professional bodies and associations apply.
