Inter departmental Flexibility (I.D.F.) is included in the policy, which governs the operation of your vessel, and as such forms part of your contract of employment. I.D.F. means that irrespective of your Rank and the Department to which you are allocated, you will be required to assist as appropriate anywhere in the ship as instructed by your Head of Department or the Master. This means that the best use is made of all available manpower onboard to ensure the vessel is operated efficiently and maintained in a first-class condition. This, in turn, will make life onboard safer and more comfortable for you and your fellow shipmates.
