Kronos Workforce Central Legacy Data Access — Indefinite, Without WFC

Kronos workforce central legacy data access is the consumer-facing capability — for ex-employees, auditors, regulators, finance retro-query staff, legal counsel and HR partners — to retrieve historical WFC data after the active tenant has been migrated to Fusion or fully retired. The use cases are not operational: they are evidentiary (FLSA audit, state wage class action), administrative (ex-employee verification, FMLA re-open), regulatory (DOL Wage & Hour, IRS payroll examination) and analytical (year-over-year labor trends, retroactive premium pay analysis). Syntra ETL delivers legacy data access via SQL query layer + web UI + signed evidence packs over the cloud archive, indefinitely after WFC EOL.

Six consumer groups in order of request frequency. (1) HR partners answering ex-employee verification requests (employment dates, hours worked, final accrual balance). (2) Payroll analysts handling retroactive premium-pay corrections and year-end W-2 substantiation. (3) Legal counsel responding to state wage class actions, FMLA disputes, ADA accommodation reviews. (4) Auditors running SOX walkthroughs, DOL Wage & Hour investigations, IRS payroll examinations. (5) Union representatives accessing grievance evidence with proper request authorization. (6) Finance analytics teams running multi-year labor cost and overtime concentration analysis.

Driven by retention obligation, not preference. FLSA: 3 years for payroll, 2 for timecards. State wage law: 4-7 years depending on jurisdiction. FMLA: 3 years. IRS payroll: 4 years from due/paid. Union contracts: commonly 5+ years for grievance windows. State public records (for public employers): often indefinite. Most customers settle on 7–10 years of legacy data access post WFC cutover to cover the longest applicable retention. Beyond that, retention policy drives tier-out and (where contract permits) deletion. The marginal cost of an extra year on object storage is trivial versus the cost of being unable to respond to a legitimate request.

No — and this is the point. Once the WFC tenant is retired (Kronos Private Cloud Dec 2025 / on-prem Mar 2027 EOL), there is no Kronos subscription to renew, no Kronos admin to call, no Kronos vendor support to escalate to. Legacy data access lives entirely on Syntra ETL's cloud archive (Parquet on object storage + SQL query layer + web UI) and is independent of any Kronos or UKG operational dependency. Access continues indefinitely, governed by retention policy, with the same query response and evidence-pack signing that was available pre-retirement.

Generally no — direct ex-employee access raises HIPAA, FCRA, state PII and union access concerns that most HR departments are not willing to delegate to self-service. The standard pattern is: ex-employee submits verification request to HR (commonly via the employer's standard verification portal); HR partner uses kronos workforce central legacy data access web UI to pull the verification data; HR delivers to the requester (background-check firm, unemployment office, mortgage underwriter, etc.) with the standard authorization-on-file model. The legacy access layer makes the HR partner's response time-to-completion drop from days to minutes.

Three layers of control. (1) Authentication: SSO with MFA, role-based access (HR partners see HR data, legal counsel sees legal-relevant data, audit sees everything with read-only); no shared accounts. (2) Authorization: per-record access decisions based on role + business unit + jurisdiction, with audit-required justification for sensitive pulls (e.g., union member records, executive comp). (3) Logging: every query logged with user-id, timestamp, query parameters, result row count, signed evidence pack hash; logs are themselves audit artifacts. This satisfies SOX who-queried-what evidence, state PII access logging requirements, and union member-data-access agreements.

For pre-built template queries (FLSA pull, accrual snapshot, FMLA detail, ex-employee verification, union grievance evidence): sub-30-second query response, additional 5–10 minutes for signed evidence pack generation. For ad-hoc analytical queries via SQL: response scales with result size, typically sub-minute for single-employee multi-year, single-digit minutes for bulk state-wide pulls. For state class action evidence demands spanning millions of records: bulk extracts run with parallel workers and return in proportion to result size, typically hours. Compare to defunct-WFC-tenant recovery, which is often impossible.

Yes. The cloud archive that holds retired WFC data can extend to capture Fusion Time & Labor data as it ages out of Fusion's operational window (typically 2-3 years). A unified legacy access layer covers both Kronos-era and Fusion-era data with consistent schema, unified query templates, and merged result sets for queries that span the cutover. This is increasingly the pattern customers adopt — build the kronos workforce central legacy data access layer once for the WFC EOL, then extend it as the long-term WFM history layer that survives the next platform change after Fusion.
