Neither/Nor Agreement and a Ambiguous “Which” in a Handbook
Brightline People Ops is finalizing a 240-employee handbook that will be issued in English and five other languages. A sentence in the lockout/tagout section reads: “Neither the shift supervisor nor the technicians has completed the checklist, which was due Friday.” Two proofreaders disagree. One argues has is correct because neither is singular; the other argues have is correct because technicians is nearer the verb and the sentence sounds wrong otherwise. The style guide says to follow Chicago on agreement but also says handbook language must be unambiguous for employees reading in a second language. A union representative has separately complained that the sentence does not say who must complete the checklist, and that which could refer either to the checklist or to its completion. The file goes to the printer in 48 hours; a full legal review is not available, but the operations director can approve one rewritten sentence. The editor must resolve the agreement question, remove the ambiguity, and decide whether a parenthetical explanation is worth the added length.
1. Should the verb be “has” or “have”? Justify your choice using the style guide, the grammar, and the audience.

The verb should be have. The construction is neither X nor Y, and the guide adopts Chicago, which uses the proximity principle: the verb agrees with the nearer subject. Here the nearer subject is technicians, plural, so have is the controlled choice. The proofreader who argues for has is applying the rule for neither alone, where singular agreement is normal: Neither has completed it. That rule does not automatically extend to a neither … nor pair with a plural second element.
The audience consideration reinforces the choice. Employees reading in a second language are likely to parse the sentence left to right and to treat the noun immediately before the verb as the subject. Technicians has creates a jarring mismatch that can obscure who has not completed the checklist, which is the opposite of what a safety section needs. I would not defend has as “more formal” here; it is defensible only under a different style decision, and the guide has already made that decision.
2. Rewrite the sentence to remove the ambiguous “which” and, if possible, clarify responsibility. What can and cannot be fixed without new policy information?

The ambiguity has two layers. The first is attachment: which was due Friday can describe the checklist or the completion. The second is responsibility: the original says who has not completed the checklist but not who was required to. Grammar can fix the first; policy must fix the second.
A safe rewrite is: “Neither the shift supervisor nor the technicians have completed the lockout/tagout checklist that was due Friday.” Changing which to that makes the clause restrictive and attaches it to checklist, so the deadline clearly belongs to the checklist. The agreement is now have. This rewrite does not invent a duty statement.
If the operations director confirms shared responsibility, a stronger version is: “The shift supervisor and the technicians must each complete the lockout/tagout checklist by Friday; as of today, neither the supervisor nor the technicians have done so.” That version assigns responsibility, but the editor should not adopt it without confirmation, because it changes the policy meaning rather than only the grammar.
3. Is a parenthetical explanation worth adding? Decide within the 48-hour constraint and explain the trade-offs.

A parenthetical is probably not worth it. The sentence is in a safety section, but the problem is not a technical term that needs defining; it is a structural ambiguity that can be removed by rewriting. A parenthetical such as “(the checklist, not its completion, was due Friday)” adds length, adds translation cost across five languages, and invites the same attachment problem in the translations. It also looks like an afterthought in a handbook that is supposed to read as policy.
The better use of the 48 hours is to get one operations-approved sentence, send it to the translators with a note explaining the intended attachment, and ask them to preserve the restrictive structure in their languages. If the director cannot confirm responsibility before the deadline, publish the neutral that version and add responsibility in the next revision. That is a smaller risk than inserting an unapproved duty statement or a bulky parenthetical.
