Eight lines, four couplets, not a single punctuation mark: Dave Bonta's "Graveyard shift" sounds like something muttered at the end of a long night and then, quite suddenly, like something screamed. Its subject is night work, but it cares less about the timetable than about what the timetable does to a person. Its central idea is that a job taken only for the money can leak out of its own hours and into the mind, until the worker is begging for an emergency, almost violent release.
The opening is deliberately flat. "what work I do / is to get some money" is the language of a shrug. Work is a means and nothing more, and the money is merely "some." The second couplet adds a condition: the speaker wants *not so much* money that "my pretty hands / come to grief." "Pretty" is a strange word here, faintly vain and faintly self-mocking. The poem never says what the hands are for. What matters is that they are the speaker's treasured possession, and the bargain is to give up as little of oneself as possible. The line sprawls, as the longest in the poem, and then drops onto the short, bleak "come to grief." As an idiom it just means "to be ruined." But set beside a title that contains a graveyard, "grief" starts to sound like mourning, and the first hint of death arrives in the most casual-sounding line.
The grammar changes in the third couplet. Everything so far has been statement; now come two commands with no one named to obey them: "trepan my head," "pierce this night." The missing addressee could be a surgeon, the darkness itself, God, or the reader, and the blankness makes the lines read like a prayer and a curse at once. "Trepan" is a rare, clinical word. It means drilling a hole in the skull, an old procedure that people sometimes imagined as a way of letting trouble escape. Against the casual "pretty hands," it lands hard. The enjambment also makes the next line slippery: "carrying about bad music" can describe the head, or the speaker wandering around with it. Judging by the imagery, the "bad music" is something like an earworm, the grinding noise of repetitive work, or low-grade dread. The poem doesn't say, and that vagueness lets any tired reader supply their own.
The last couplet turns the night itself into a body. We pierce a boil or an abscess to let the poison out, so "pierce this night / to let the plague out" makes the darkness swollen and infected. Head and night mirror each other, since both are containers with something rotten inside. The escalation is sharp. What began as "bad music," an annoyance, ends as "plague," an epidemic. The word also completes the death-theme begun by the title and by "grief." The demonstrative "this" matters too. The speaker is not remembering the night shift but still inside it.
Sound reinforces the surgery. There is no rhyme and no regular metre; the lines are short and uneven, with the stress falling where speech would put it. But the poem is full of plosive *p*'s: "pretty," "trepan," "pierce," "plague." Each is a tiny puncture of breath, and they gather towards the end, so the poem's own sounds anticipate the piercing it demands. The lowercase, unpunctuated lines also mean no sentence ever formally stops. The final word, "out," is an exit, but there is no full stop to close the wound behind it.
The poem's significance lies in how much it packs into so little. In eight lines it holds the economics of low-paid work (the modest, grudging "some money"), the body (hands, skull), and the atmosphere of the night, then lets them bleed into one another. Its tonal swing from wry understatement to desperate imagery is the real drama. The poem suggests that the price of a bad job is not only tired hands but a mind that cannot stop playing the wrong tune, and it makes that point so briefly that it is hard to forget.
