vacancy

vacancy
A post which an employer intends to fill if a suitable applicant appears. The number of job vacancies is difficult to measure, as there is no one standard method of advertising or filling them. Job information is circulated by official and private employment agencies, public advertisement, and word of mouth among present and past employees. While some employers have very clear-cut ideas on how many vacancies they wish to fill, others follow an elastic policy, taking on promising candidates as they appear.
