Worker with broad-based, non-specific skills
Roustabout (Australia/New Zealand English: rouseabout) is an occupational term. Traditionally, it referred to a worker with broad-based, non-specific skills. In particular, it was used to describe show or circus workers who handled materials for construction on fairgrounds. In modern times it is applied to rural employment, such as those assisting sheep shearing, and positions in the oil industry.
Oil industry in the US.
"Oil roustabout" refers to a worker who maintains all things in the oil field. Roustabout is an official classification of natural gas and oil rig personnel. Roustabouts working in oil fields typically perform various jobs requiring little training. Drillers start off as roustabouts until they gain enough hands-on experience to move up to a roughneck or floorhand position, then to driller and rig supervisor. Roustabouts will set up oil well heads, maintain saltwater disposal pumps, lease roads, lease mowing, create dikes around tank batteries on a lease, etc. An oil roustabout has no limits in the oil industry and can, and will do any and all oil field work, including roughneck drilling, oil well completion and well service, and even chemical work. An oil field roustabout will also do all things that an oil field pumper would have to do. However, they frequently turn out to be long-term employees and take on more difficult and sometimes dangerous jobs as they gain experience. Most go on to at least become “roughnecks” if they work for the rig company for more than a few months.
An early 2010 survey by Careercast.com of the best and worst jobs based on five criteria—environment, income, employment outlook, physical demands and stress—rated 'roustabout' as the worst job. Nonetheless, the anecdotal and subjective experience of an actual roustabout suggests that for some, it can be a challenging, adventurous job.
