Being a husband is a whole-time job.

Taken at face value, Bennett’s line treats marriage not as a status but as sustained labor: to be “a husband” is to perform ongoing duties—emotional attentiveness, practical support, and moral responsibility—rather than to enjoy a title. The phrase “whole-time job” (a period idiom for full-time employment) underscores constancy: the role does not switch off after working hours. The remark also carries a dry, Bennett-like realism about domestic life, implying that successful partnership requires deliberate effort and discipline, not merely affection or social convention.
