The management can try to send an aircraft off without enough fuel to reach its destination, hoping that favourable winds will enable the flight to be completed. However, they shouldn't be too surprised when their aircraft regularly divert en-route to refuel. The people who suffer are the passengers (not being on schedule) and shareholders (due additional operating costs as a result of "un-planned" diversions and tech. stops). Safety is not compromised as long as you have properly qualified flight crews who will divert when they have to.
