Jobs and occupations emerge and develop over time. We can see a mix of this reflected in both the updating systems of the O*NET taxonomy1 and in the studies of on-line job postings which capture new and additional skills being appended to current jobs and occupations2. In both cases we are witnessing a dynamic situation where work is changing – sometimes radically so. It is been stated by some there is a near natural polarisation occurring in the labour market with a hollowing out of the middle skill range of jobs3. It is also likely that these changes are a subset of the wider changes in the economy being driven by major waves of technological change, made up of specific technologies and wholly new technological systems4. These wider changes operate over lengthy periods of time i.e. 200+ years5. But what are we potentially witnessing here as regards the changing nature of work? Are hybrid jobs a natural part of the labour market? Do the long waves of technological change suggest any patterns of skills formation?

For the US economy, O*NET identifies 153 (14%) new and emerging occupations out of a total of 1102. Six major occupational groupings account for 86% of these6. So even at the level of a national occupation information system, occupational change can be detected during the usual annual update process and the specific efforts to identify groupings of changing occupations – for example, those in the green economy. Analysis of online job postings identifies 250 occupations (23% of the total) as being hybrid (and changing)7.

So, taken together, there are potentially over 400 occupations which are either hybrid or new and emerging – i.e. 40% of all occupations (but there will be some double counting here).  This level of change shows the dynamic nature of work and the difficulty of being over-specific about a large amount of the content of an occupation at any moment in time. This is further compounded among low skill occupations, where the incumbents undertake the bulk of their work only using two prime skills8. What is not clear is the relationship between hybrid and new and emerging occupations, and when one becomes the other i.e. hybrid creating new core activities enough to define new occupations. Some aspects of hybridisation will not lead to new occupations but will rather be a new set of skills, knowledge and abilities relevant to multiple occupations. An example of this is the use of many software packages.

Here are some other trends that may be relevant in explaining the hybridisation of roles:

  • Growth of self-employment and micro-businesses9: Self-employment and micro-businesses can supply many specific and new skill sets. Self-employed people are often forced to acquire a wide range of skills and to naturally hybridise themselves to meet customer requirements.
  • Whole task/process-focused organisation philosophy10: Over time, there has been a shift towards designing and organising de-fragmented work – and in the process de-skilling and routinising it – and moving towards a process-focused, whole task capability. This trend also could mean that those medium and low skilled occupations threatened by artificial intelligence and automation could be reconfigured to provide transition paths away from job degradation and elimination.
  • Mass customisation11: Initially a concept pursued by manufacturing seeking to reach the optimum batch size of one, we have seen this concept enter education, retail, clothing and textiles, health and medicine, construction and transport. The trend is towards maximising choice and seeking to meet specific customer, consumer, client and patient needs. This trend increasingly pulls work content towards being packaged around whole solutions which requires multi-tasking and multi-skilling.
  • Regulation and risk management12: In order to protect people at work, the consumer from sub-standard products and services, etc. regulation is a major driver for change, and it revolves around the level of risk we are willing to take as a society, as an organisation, etc. and which calls for greater discretion and capability in the roles of the people who have to manage the risk on a day-to-day basis. Again, this drives hybridisation of roles.

It is reasonable to conclude that hybrid roles are part and parcel of the labour market and occupations are constantly picking up and dropping tasks and skills as technology and customer requirements change. The emergence of online education and training systems and qualifications support the hybridisation of occupations by allowing incumbents to acquire, develop and master the required new skill sets13.

For the methodology see: National Centre for O*NET Development (2009) New and Emerging Occupations of the 21st Century: Updating the O*NET SOC Taxonomy. Summary and Implementation. Prepared for the US Department of Labor, Washington DC. 19 pages. It is worth noting that an occupations is added to the O*NET taxonomy if it meets the following two criteria: (i) the occupations involves significantly different work than that performed by job incumbents of other occupations; (ii) the occupation is not adequately reflected by the existing O*NET SOC structure (p10). In 2006 only 6 occupations were added to the O*NET new and emerging occupation list, and by 2009 this had risen greatly to 153. The O*NET is also linked to the emerging demand for new skills through its tracking system across what are termed “in-demand industry clusters” (see: ) od which there are seventeen in all of which are multi-sectoral and could economy wide in their impact. O*NET take this one stage further for some changing parts of the economy i.e. green/sustainable parts and produce a task level green database.
