Corrections Policy

Last Updated: June 2026

Opora Supply publishes operational reference content for the commercial cleaning industry, including production-rate methodology, wage benchmarks, regulatory citations, and bidding mechanics. Accuracy is the precondition for that content being useful. This policy describes how we identify, correct, and disclose errors in published articles, tool outputs, and methodology pages.

Scope

This policy applies to all editorial content on www.oporasupply.com, including:

  • Hub pillar pages and cluster articles in the Field Guide
  • Calculator and tool methodology pages
  • Glossary entries
  • Programmatic content (PFAS state lookups, metro wage tables, state licensing references)
  • Cheat sheets and downloadable resources

It does not apply to product listings, store policies, or transactional communications, which are governed separately by our Terms of Use and Privacy Policy.

Error categories

We classify errors into four tiers, which determine the response.

Tier 1 — Factual error in a cited figure, regulation, or primary-source claim. Examples: a misquoted OSHA section number, an incorrect BLS wage figure, a misstated NCCI split point, a misattributed citation. Tier 1 errors are corrected within five business days of confirmation, and the corrected article carries a visible correction note (see below).

Tier 2 — Methodology error or formula error in a calculator, tool, or worked example. Examples: an arithmetic error in a published example, an incorrect dilution-ratio calculation, an off-by-one error in a fixture-count formula. Tier 2 errors are corrected within five business days, the tool or worked example is updated, and the correction is logged on the affected article and on the Methodology page where applicable.

Tier 3 — Outdated regulatory citation, wage figure, or standard. Examples: a BLS figure that has been superseded by a more recent release, an OSHA rule that has been amended, an ISSA cleaning-time edition that has been updated. Tier 3 corrections are addressed in the article's normal review cycle (annually for evergreen content, sooner for rapidly changing data) and are reflected in the article's "Last Updated" date and source-vintage disclosure.

Tier 4 — Typo, broken link, formatting error, or non-substantive edit. Tier 4 fixes are made silently in the article without a correction note. The "Last Updated" date is refreshed.

How errors are identified

Errors reach us through three channels:

  1. Reader reports. Every article carries a "If you spot an error in this article, contact us" link in its disclaimer. We treat these reports as the primary input.
  2. Internal review. Articles are reviewed on a cycle, with priority for content that cites volatile data (wage rates, regulatory citations, tax-year-specific figures). Tools and methodology pages are reviewed before each release.
  3. Source-monitoring. When a primary source publishes a material update (a new BLS OEWS release, a revised OSHA standard, a new ISSA edition), affected articles are queued for review.

How errors are corrected

When a confirmed error is identified, the workflow is:

  1. Verify the correct value or claim against a primary source. A reader report is a flag, not a conclusion; the editorial team confirms the correct figure against the original government, standards-body, or industry-association source before changing the article.
  2. Edit the article. The incorrect figure, claim, or citation is replaced with the verified correct version.
  3. Update the article's "Last Updated" date. Every substantive edit refreshes this date.
  4. Append a correction note (Tier 1 and Tier 2 only). A visible correction note appears at the bottom of the article, above the disclaimer, in the format: "Correction (Month YYYY): The previous version of this article stated [original incorrect claim]. The correct figure is [corrected claim], per [primary source]. The article has been updated."
  5. Update related content if applicable. If the same error appears in a glossary entry, cheat sheet, or tool description, those assets are corrected in the same update.

Disclosure standard

Correction notes describe what was wrong and what is now correct. They do not silently remove the original error or rewrite history. The standard for what triggers a visible correction is straightforward: if a reasonable reader could have made a different operational decision based on the incorrect figure (a bid, a staffing plan, a compliance step), the correction is disclosed.

For Tier 4 fixes (typos, broken links, formatting), we do not append a correction note because the substantive content has not changed. Refreshing the "Last Updated" date is the only acknowledgement.

Reader reports

To report a suspected error, contact us. When you contact us, the report is most useful when it includes:

  • The article title or URL
  • The specific figure, claim, or citation in question
  • The source you believe is correct (a link to the primary source is ideal)

We acknowledge reader reports and, where the report results in a correction, the correction note credits the report generically ("a reader report identified..."). We do not publish reporter names without explicit permission.

What we do not do

We do not retroactively edit published articles to remove or rewrite claims that were correct at the time of publication and have since become outdated. Outdated content is updated through the Tier 3 process described above, with the "Last Updated" date and source vintage making the change transparent. This preserves the record of what was published and when.

We do not remove correction notes after a correction has been made. Once a correction note is appended, it remains as a permanent disclosure on the article.

We do not correct content to favor a vendor, advertiser, or commercial partner. Editorial decisions, including corrections, are independent of commercial relationships.
