The answer depends on the role, roster and employment terms. Weekend work is possible, but it does not mean every worker must be available all the time. Check the applicable award or agreement and ask for a clear roster before accepting a job.
If you are worried about burnout in property management, examine how the work is organised. A sustainable role needs clear priorities, enough support and a workable response to urgent issues. Personal effort alone cannot repair an overloaded system.
Safety at a property visit should be planned by the workplace. It should not depend on a worker being brave, reading a stranger perfectly or managing every risk alone. Ask about the system before you accept lone visits.
