Job websites, websites of cleaning and janitorial companies and corporate websites' careers sections list office cleaning jobs. Office cleaning positions may also list as custodial, janitorial or building maintenance positions.
Job websites include Indeed.com and craiglist.org. Indeed searches other job sites for positions, so jobs from Monster, CareerBuilder and similar job sites are viewable in one place. Craigslist.org's cleaning jobs may be in the admin/office, general labor, part-time or services sections. GovernmentJobs.com covers openings for cleaning government offices.
Janitorial companies, such as Professional Building Services, may list their jobs in the Employment section of the company websites and also on job sites.
Related positions to consider include hospital, nursing home, apartment complex and school cleaning jobs.
