By all the usual standards, he should be promoted to head Quality Control. Yet, John Crane now has doubts. He has frequently smelled alcohol on Pullman's breath. Pullman apparently drinks on the job. Crane has never seen him drunk, unable to perform.
Every drunk begins as a drinker, no doubt, but most drinkers remain drinkers.
Equally important, we are not very good at predicting who will be a good manager. The only reliable way to find out whether Pullman can take the pressure is to give him the chance. Pullman does have a problem. He likes to drink on the job and his company now has a policy against that. Crane has a problem too.
