Out of Hours & Weekend Support
This role includes a rotational element of out of hours and weekend airtime enquiry support, typically on a one weekend in four rota basis. Our maritime customers operate around the clock, and occasional responsiveness outside standard hours is part of keeping them connected. Weekend support shifts are fully compensated with equivalent time off in lieu, ensuring your work life balance remains protected. Candidates who are flexible and comfortable with occasional on call responsibilities will thrive in this aspect of the role.
