These factors make this occupational group relatively easy to enter. Most workers in this occupational group were either janitors , caretakers or building superintendents in 1998. The highest growth rate is expected for cleaners who work in the growing accommodation sector due to rapid growth in tourism. New technology is expected to have little effect on the employment of cleaners . Robots are limited to a single cleaning task and may not be usable in many places, particularly cluttered areas such as hotel and hospital rooms.
Interpersonal skills are very important for janitors , caretakers and building superintendents .
Employers often prefer persons with some construction background and those who can undertake building maintenance to fill positions in these occupations. Progression to supervisory cleaning positions is possible with additional training or experience.
