CCNL Igiene Ambientale — Servizi Ambientali e di Igiene Urbana¶

igiene-ambientale-utilitalia/industria_rates_proxy · inps_employer · impact unknown · open

INPS RATES. INDUSTRIA rates from 2026-industria.json used as proxy (3 size tiers: ≤15, ≤50, >50 employees — selected via Employer.num_employees). For K540 (igiene ambientale), the applicable CIGO regime is standard industria (CIGO ordinaria) under D.Lgs. 148/2015; no sector-specific INPS circular found. The CIGO addizionale (0.60% ≤50 employees, 0.90% >50) is event-driven: charged only when hours are actually in CIG integrazione — correctly excluded from the standing monthly rate. Simplification: industria proxy, not a sector-specific file.

Applies when: inps_employer applies.

Remediation: Verify the INPS rates of igiene ambientale against a sector-specific circular.

igiene-ambientale-utilitalia/apprentice_seniority · seniority · impact unknown · open

APPRENTICE SENIORITY: the CCNL text read for this ruleset does not state whether apprentices accrue the level seniority increments or an amount of their own, and no apprentice amount is modelled. The engine pays no increment during the apprenticeship (provisional); the run is affected when the apprentice has matured increments the level pays.

Applies when: seniority applies; the run takes the engine code path; contract type in apprentice.

Remediation: Source the CCNL clause on apprentice seniority and model it as seniority_increments.apprentice_amount (zero when apprentices accrue none), then remove this note.

igiene-ambientale-utilitalia/fund_paid_month · pension_fund_contribution · impact yes · open

Previambiente is due on the pay of the month (art. 65 c. 8): none for a month without pay, and 'commisurato alla retribuzione corrisposta' for a month with a paid absence, a rule the engine does not compute. A month paid in part (an unpaid absence, sickness, a partial month) keeps the full contributions of an enrolled worker.

Applies when: pension_fund_contribution applies; the run takes the engine code path.

Remediation: Source how the contributions are proportioned to the pay of a month paid in part, model it, then remove this note.

igiene-ambientale-utilitalia/contractual_fund_partial · pension_fund_contribution · impact unknown · open

The Previambiente contractual contribution (5 EUR, 15 EUR for a worker not enrolled voluntarily) is owed in full on a partly employed month; the CCNL states no rule for it.

Applies when: pension_fund_contribution applies; the run takes the engine code path.

Remediation: Source the rule of art. 65 for a partly employed month, model it, then remove this note.

sickness_inps_daily_base · sickness · impact unknown · open

The INPS share of a sick day is the INPS rate times the CCNL daily quota of the current month, counted on the CCNL payable days. INPS computes it on its own daily base (retribuzione media globale giornaliera of the month before) and on calendar days. The worker's total for the day is the same; the split between INPS indemnity (outside the contribution base) and employer integration may differ, and with it the contributions.

Applies when: sickness applies; the run takes the engine code path.

Remediation: Compute the INPS indemnity on the INPS daily base and calendar days of the INPS rules, with the pay of the month before, then resolve this limitation.

sickness_cumulation_window · sickness · impact unknown · open

The CCNL tier and the comporto are counted on the days of one episode and the relapses it continues. A CCNL that sums the sickness of separate episodes over a window (a calendar year, the last three years) can reach a lower tier or the end of the comporto earlier than the engine shows. The run is affected when an earlier episode outside the relapse chain is recorded.

Applies when: sickness applies; the run takes the engine code path.

Remediation: Add the cumulation window of each CCNL to its sickness rule, with the source, and count the tier and the comporto over it.

provisional_ruleset · irpef · impact unknown · open

The run reads a tax ruleset marked provisional: the sources of its year are not published yet (budget law of the year; regional and municipal surtax resolutions), so the values are those of the year before, carried over. Rules in force by statute (the IRPEF brackets of art. 11 and the deductions of art. 13 of the testo unico of D.Lgs. 117/2026) carry over unchanged; any change of the budget law is not applied.

Applies when: irpef applies; the run takes the engine code path.

Remediation: Replace each provisional ruleset of the year with the values of its published sources, drop its provisional flag, then resolve this limitation.

provisional_inps_ruleset · inps_employer · impact unknown · open

The run reads an INPS ruleset marked provisional: the INPS circulars of its year are not published yet, so the rates, the massimale and the minimale (and the hourly contributions of domestic work) are those of the year before, carried over. The indexed amounts change every January: the carried-over values understate them.

Applies when: inps_employer applies; the run takes the engine code path.

Remediation: Replace each provisional INPS ruleset of the year with the values of the INPS circulars of the year, drop its provisional flag, then resolve this limitation.

tfr_compensation_apprentice_guarantee_fund · inps_employer · impact yes · open

An apprentice whose TFR goes to a pension fund or to the Fondo Tesoreria takes the 0.28-point relief of D.L. 203/2005 art. 8, but not the exemption from the 0.20% Fondo di garanzia contribution of D.Lgs. 252/2005 art. 10 c. 2: no source found says whether the apprentice rate (10% of L. 296/2006 art. 1 c. 773 plus NASpI and the integration funds) holds a Fondo di garanzia share to exempt. The employer contributions of the run may be overstated by 0.20% of the INPS base.

Applies when: inps_employer applies; the run takes the engine code path; contract type in apprentice.

Remediation: Find an INPS source on the Fondo di garanzia share of the apprentice rate, then exempt it with the other workers or record that none is due.
