Current UK CAA FTL limits you to 4 consecutive night duties. Thus 4 on 4 Off. As the rest of the DHL network runs 8 on 6 off and EAT are talking of either 7/7 or 14/14 dont expect 4 and 4 to last very long. UK companies are at a significant disadvantage when compared to their EU competitors in regards of night scheduled freight so there is considerable pressure for the CAA to change the rules.
