Why not just trust a compliance newsletter or blog post?

Secondary sources are useful for awareness but can lag, oversimplify, or misstate an effective date. Before changing a policy or handbook, confirm the actual legal text and effective date at the primary source, the agency or legislature that issued it, since that is what would matter in an audit or dispute.

What is the difference between a bill passing and a law taking effect?

A bill becoming law (signed by the governor or president) and a law's effective date are often different dates. Many state laws specify a delayed effective date, sometimes months or over a year later, so check the effective date specifically, not just the signing or passage date.

Where is the single best starting point for federal changes?

The Federal Register, at federalregister.gov, is the official daily publication for federal rules, proposed rules, and notices from agencies including the DOL and EEOC. It is the primary source federal agencies themselves use to publish binding rule changes.

How to Verify an Employment Law Change at the Primary Source

Short answer: Before updating a handbook, policy, or payroll system based on a reported employment law change, confirm it at the primary source, the actual agency or legislature that issued it, rather than relying solely on a secondary summary. For federal changes, that means the Federal Register (federalregister.gov) and the issuing agency's own site (dol.gov, eeoc.gov). For state changes, that means the state legislature's own bill-tracking site and, once effective, the state labor department's published guidance. Check the effective date specifically, it is often later than the date a bill was signed.

Why verification at the primary source matters

A secondary source, a newsletter, a blog post, a summary from a vendor, can be accurate and still lag the primary source by days or weeks, oversimplify a nuanced threshold (who is covered, at what company size, in which industries), or simply get an effective date wrong. None of that matters much for general awareness. It matters a great deal if you are about to change a handbook, adjust a payroll system, or make a compliance representation, where being wrong has real cost. The primary source, the actual statute, regulation, or agency guidance document, is what would be checked in an audit or dispute, so it is worth the extra few minutes to confirm there directly.

For federal changes: three sources

The Federal Register (federalregister.gov): the official, daily publication of federal agency rules, proposed rules, and notices. Every DOL or EEOC rule change that has gone through formal rulemaking is published here, with the exact regulatory text and its effective date.
The issuing agency's own site: dol.gov for wage, hour, leave, and OSHA-related changes; eeoc.gov for discrimination and harassment guidance; nlrb.gov for labor relations rules. Agencies typically publish plain-language summaries alongside the formal Federal Register text.
The regulation text itself: for a rule that has been finalized, the Code of Federal Regulations (CFR), mirrored at sites like the eCFR or law.cornell.edu, contains the current, consolidated regulatory text, useful for confirming exactly what is in force right now, as opposed to what was proposed or what changed historically.

For state changes: two sources, and they are state-specific

The state legislature's own bill-tracking site: every state publishes its own legislative record, bill text, vote history, and signing date. This confirms a law actually passed and was signed, and gives you the bill's exact text.
The state labor department's own guidance: once a law is enacted, the relevant state agency (see our DOL vs state labor departments guide for how to find yours) typically publishes implementation guidance, FAQs, or updated posting requirements. This is usually the most practical source for "what do I actually have to do," as opposed to the raw bill text.

There is no federal shortcut here, each state runs its own legislative site and its own labor department site, independently, so a multi-state employer has to check each relevant state separately.

The effective date trap

The single most common verification mistake: confusing the date a bill was signed into law with the date it actually takes effect. Many state employment laws specify a delayed effective date, sometimes a full year or more after signing, to give employers time to prepare. A change reported in the news the week a bill is signed may not require any action from you for months. Always look specifically for the phrase describing when the law "takes effect" or "is effective," not just when it was enacted or signed.

A simple verification checklist

Identify the specific claim: what changed, and who told you (a newsletter, a vendor digest, a news article)?
Find the primary source: Federal Register or agency site for federal; legislature bill text and state labor department guidance for state.
Confirm the effective date specifically, not the signing or passage date.
Confirm the scope: which employers are covered (by size, industry, or location), and which employees.
Note the date you verified it, so you have a record of when your understanding was current.
