A maintenance supervisor oversees the maintenance crew for a business, building, complex, or campus. As a maintenance supervisor, your primary responsibility is ensuring that your team completes all maintenance tasks and repairs promptly, and to the standards of your employer. You may also be responsible for submitting schedules and payroll, as well as interviewing and hiring new workers. Your job is both technical and managerial—you are ultimately responsible for the wellbeing of the building systems as well as the management of your team of workers.
