Everyone has had it. The aches, the pains, the sweats and the wracking cough.
But smart-thinking agency bosses at Duckworth Finn Grubb Waters were one step ahead of one of the most fearsome flu bugs to strike the marketing community.
Staff were offered the chance of a flu jab at the beginning of the winter so that the agency could carry on those all-important new business pitches.
Nevertheless the agency has not escaped scot-free. Some members of staff have still gone down with the bug, although it is not known whether they took the precaution of having the free flu jab.
