You are a PI and have hired a technician (female). Your lab's research occasionally requires work after hours and on weekends to monitor experiments or to complete critical analyses. After a few months, the new technician expresses fear at working in a nearly deserted building and asks to be excused from such work. The security at your workplace is not great, but there have never been any "incidents". You have other staff who routinely perform after-hours research. Are you obligated to agree to the new technician's personal preferences?
