Office cleaning jobs that involve working at night are almost always in demand because of the odd hours and the sometimes intense workload. Individuals who are in this position are expected to perform many basic janitorial duties such as vacuuming, cleaning bathrooms and dusting surfaces. There might also be other maintenance duties like replacing light bulbs, moving furniture between conference rooms and refilling water coolers. The job takes place at night so that the cleaning staff does not disturb workers during the day with loud equipment or constant interruptions. Office cleaning jobs at night do not require extensive educational backgrounds except a high school diploma. The position requires a large amount of trust in the staff and normally requires a criminal background check. Individual qualifications include the ability to lift 20 pounds or more, the ability to move actively and change positions for several hours without a break and a schedule that is not affected by working at night. Additionally, many employers look for a person who owns reliable transportation and who can work well as part of a larger team. Nighttime office cleaning jobs are frequently posted in the help wanted section of local papers and on job boards. The positions are all fairly standard so the primary consideration should be the convenience of the building and any additional benefits that the work might provide. Students who are looking for this type of position can often find work through the college or university that is being attended. It is possible to find a job by approaching the facilities manager of a large building or warehouse and asking if there is any work available. Temporary staffing agencies can also help to locate a position in this field because many jobs are part-time and have a high turnover. Most office cleaning jobs at night start new employees at just above minimum wage. Higher starting salaries are available to individuals with experience or a higher education. Certain companies offer slightly better starting salaries for nighttime employees because the job is harder to fill. The positions offer little room for advancement with the exception of becoming a manager or team leader in larger buildings. Most salaries rise as an employee gains more experience but tend to not exceed $22,000 each year on average.
