From 4210362392bf72785275c5331eebec8506f84453 Mon Sep 17 00:00:00 2001 From: MOHITKOURAV01 Date: Thu, 27 Aug 2026 22:19:21 +0530 Subject: [PATCH 001/140] feat(suspensions): the section 10A scale, the attributability finding the uplift turns on, and the set-off on reinstatement (#1828) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `salaryCalculator.js` can pay somebody and `settlement.js` can stop paying them. There is a third state neither can hold: suspended pending enquiry, where the employment subsists, no work is done, and the employer must pay on a rising scale. Recording it as loss of pay pays nothing, and non-payment is an offence under section 10A(4) whatever the enquiry eventually finds. The scale is not date arithmetic. The uplift from fifty per cent to seventy-five on day ninety-one is conditional on a finding — whether the delay in completing the enquiry is attributable to the workman — so `ATTRIBUTABILITY` is a required argument and `NOT_DETERMINED` does not uplift. Defaulting the other way overpays by silence, and the only correction available afterwards is recovery. There is no route that sets the rate. The rate is a consequence of the finding, and an overridable rate would let the stored number stop saying whether a finding was made — which is the one thing an enquiry record has to evidence. So `recordAttributability` demands a reason and stamps who gave it, and the module prices what a finding in the workman's favour would add, because a rupee figure attached to a deferral is harder to defer than "somebody should look at this". The wage base is basic and dearness allowance — a fourth definition of wages in this tree, so it is named — and frozen at the date of suspension, so a grade revision two years in restates nothing. --- .../src/__tests__/app.routeMounting.test.js | 2 + backend/src/app.js | 12 + backend/src/config/permissions.js | 54 ++ .../subsistenceAllowance.controller.js | 754 ++++++++++++++++ backend/src/models/auditLog.model.js | 16 + .../src/models/subsistenceAllowance.model.js | 377 ++++++++ backend/src/routes/suspensions.routes.js | 130 +++ .../__tests__/subsistenceAllowance.test.js | 445 ++++++++++ backend/src/utils/subsistenceAllowance.js | 820 ++++++++++++++++++ frontend/src/config/navigation.js | 13 + frontend/src/pages/SuspensionRegister.jsx | 590 +++++++++++++ 11 files changed, 3213 insertions(+) create mode 100644 backend/src/controllers/subsistenceAllowance.controller.js create mode 100644 backend/src/models/subsistenceAllowance.model.js create mode 100644 backend/src/routes/suspensions.routes.js create mode 100644 backend/src/utils/__tests__/subsistenceAllowance.test.js create mode 100644 backend/src/utils/subsistenceAllowance.js create mode 100644 frontend/src/pages/SuspensionRegister.jsx diff --git a/backend/src/__tests__/app.routeMounting.test.js b/backend/src/__tests__/app.routeMounting.test.js index c4940e96..ba2b4933 100644 --- a/backend/src/__tests__/app.routeMounting.test.js +++ b/backend/src/__tests__/app.routeMounting.test.js @@ -83,6 +83,7 @@ const MOUNTED_ROUTES = [ ['/api/working-hours', 'get', '/api/working-hours/limits'], ['/api/assignments', 'get', '/api/assignments'], ['/api/settlements', 'get', '/api/settlements'], + ['/api/suspensions', 'get', '/api/suspensions/rules'], ['/api/injury-compensation', 'get', '/api/injury-compensation/claims'], ['/api/esi', 'get', '/api/esi/rules'], ['/api/gratuity', 'get', '/api/gratuity/valuations'], @@ -246,6 +247,7 @@ const ROUTER_MOUNTS = { scheduler: '/api/schedules', search: '/api/search', settlement: '/api/settlements', + suspensions: '/api/suspensions', shiftRoster: '/api/shifts', minimumWages: '/api/minimum-wages', statutoryBonus: '/api/statutory-bonus', diff --git a/backend/src/app.js b/backend/src/app.js index 7a6ffd8a..b50ef3ba 100644 --- a/backend/src/app.js +++ b/backend/src/app.js @@ -84,6 +84,13 @@ const attendanceRoutes = require('./routes/attendance.routes'); const workingHoursRoutes = require('./routes/workingHours.routes'); const settlementRoutes = require('./routes/settlement.routes'); +// Section 10A of the Standing Orders Act, 1946 (#1828).

Both treat the worker as a counterparty to a contract, which is what they are. Neither can express the statutory category: an aggregator owes a share of its own turnover on account of workers who are expressly not its employees. The levy and its cap sit on two unrelated bases — one to two per cent of turnover, capped at five per cent of what was paid to workers — and which one binds is a fact about the platform's economics rather than about the statute. A delivery business whose payouts are most of its cost pays on turnover; a marketplace with thin payouts is capped and has stopped tracking turnover altogether. So `contributionFor` returns both limbs and names the one that bound, and warns while the headroom is still thin rather than after the ceiling has quietly taken over. The register is on the other axis. A gig worker registers on their own engagement and the same person may work for three platforms, each owing its own contribution — one beneficiary against three levies. So `GigWorker` is keyed on the person with engagements inside it, including platforms this tenant does not operate, because those are the days that carry most multi-platform workers past ninety. Keying on the engagement would report every one of them as short. Nothing here references the employee collection. Section 2(35) puts a gig worker outside the employment relationship, and a reference into `Employee` is the first place every headcount in the tree would start including them — so the exclusions are asserted on the result rather than left to omission. --- .../src/__tests__/app.routeMounting.test.js | 2 + backend/src/app.js | 13 + backend/src/config/permissions.js | 51 ++ .../aggregatorContribution.controller.js | 549 ++++++++++++++ .../models/aggregatorContribution.model.js | 336 +++++++++ backend/src/models/auditLog.model.js | 16 + .../routes/aggregatorContribution.routes.js | 110 +++ .../__tests__/aggregatorContribution.test.js | 415 +++++++++++ backend/src/utils/aggregatorContribution.js | 684 ++++++++++++++++++ frontend/src/config/navigation.js | 13 + frontend/src/pages/AggregatorContribution.jsx | 649 +++++++++++++++++ 11 files changed, 2838 insertions(+) create mode 100644 backend/src/controllers/aggregatorContribution.controller.js create mode 100644 backend/src/models/aggregatorContribution.model.js create mode 100644 backend/src/routes/aggregatorContribution.routes.js create mode 100644 backend/src/utils/__tests__/aggregatorContribution.test.js create mode 100644 backend/src/utils/aggregatorContribution.js create mode 100644 frontend/src/pages/AggregatorContribution.jsx diff --git a/backend/src/__tests__/app.routeMounting.test.js b/backend/src/__tests__/app.routeMounting.test.js index c4940e96..0fcf23ee 100644 --- a/backend/src/__tests__/app.routeMounting.test.js +++ b/backend/src/__tests__/app.routeMounting.test.js @@ -113,6 +113,7 @@ const MOUNTED_ROUTES = [ ['/api/search', 'get', '/api/search'], ['/api/integrations', 'get', '/api/integrations'], ['/api/compliance', 'get', '/api/compliance/config'], + ['/api/aggregator-contribution', 'get', '/api/aggregator-contribution/rules'], ['/api/email', 'post', '/api/email/webhooks'], // Mounted in #1009.

That one sentence is + * unlike every other contribution here, in three ways at once. + * + * **The base is turnover, not wages.** Provident fund, ESI, the Labour Welfare + * Fund and bonus all start from what somebody was paid. This starts from what + * the platform earned, and `complianceAggregator.js` has no access to such a + * figure and no reason to. + * + * **The cap is on a different base from the levy.** One to two per cent of + * turnover, capped at five per cent of payouts — two unrelated quantities, and + * which binds is a fact about the platform's economics rather than about the + * statute. A marketplace with high turnover and thin payouts is capped; a + * delivery platform whose payouts are most of its cost is not. So + * `contributionFor` returns **both limbs** and says which one bound. Applying + * the cap silently would hide the only interesting thing about the number. + * + * **The worker is counted on a different axis from the levy.** #1771 established + * that a headcount cannot be a single number; this is the second instance and + * the resolution is not the same. A gig worker registers on their own + * engagement, and the same person may work for three aggregators at once — each + * of which owes its own contribution on its own turnover.

That is retrenchment, and it is one of four things these chapters govern; the largest of the others is not a payment calculation at all. Lay-off is not retrenchment with a smaller number. The employment subsists, the compensation is a daily fifty per cent, and the forty-five-day ceiling is rolling — so a spell in March consumes the ceiling a spell in November needs, and by November nobody remembers March. `consumedCeilingDays` walks the other spells in the window before the engine runs, which is the one number a per-spell view could never produce. Above the Chapter VB threshold the question changes. Where prior permission was required and absent the workmen are deemed not to have been laid off and are owed all wages as if they had continued — several times what section 25C would have paid. So the result carries two liabilities under separate keys with `applicableLiability` naming the one that applies, and nothing anywhere returns their sum. A single figure either reader could take would be the most dangerous number in this product. Section 25B is recorded rather than derived. A day of lay-off counts toward the service that qualifies for lay-off compensation, a day of legal strike counts, and maternity leave counts to twelve weeks — all three read as absence to the attendance ledger, and the first two would disqualify exactly the workmen the chapter protects. The controller offers a worked-days floor and says so. This leaves #1597's section 25F calculation where it is. Where both apply, this module says whether that figure is the right one at all. --- .../src/__tests__/app.routeMounting.test.js | 2 + backend/src/app.js | 13 + backend/src/config/permissions.js | 54 + .../layoffCompensation.controller.js | 1051 +++++++++++++++++ backend/src/models/auditLog.model.js | 17 + .../src/models/layoffCompensation.model.js | 482 ++++++++ backend/src/routes/layoffs.routes.js | 178 +++ .../__tests__/layoffCompensation.test.js | 575 +++++++++ backend/src/utils/layoffCompensation.js | 997 ++++++++++++++++ frontend/src/config/navigation.js | 12 + frontend/src/pages/LayoffRegister.jsx | 543 +++++++++ 11 files changed, 3924 insertions(+) create mode 100644 backend/src/controllers/layoffCompensation.controller.js create mode 100644 backend/src/models/layoffCompensation.model.js create mode 100644 backend/src/routes/layoffs.routes.js create mode 100644 backend/src/utils/__tests__/layoffCompensation.test.js create mode 100644 backend/src/utils/layoffCompensation.js create mode 100644 frontend/src/pages/LayoffRegister.jsx diff --git a/backend/src/__tests__/app.routeMounting.test.js b/backend/src/__tests__/app.routeMounting.test.js index c4940e96..c661be01 100644 --- a/backend/src/__tests__/app.routeMounting.test.js +++ b/backend/src/__tests__/app.routeMounting.test.js @@ -84,6 +84,7 @@ const MOUNTED_ROUTES = [ ['/api/assignments', 'get', '/api/assignments'], ['/api/settlements', 'get', '/api/settlements'], ['/api/injury-compensation', 'get', '/api/injury-compensation/claims'], + ['/api/layoffs', 'get', '/api/layoffs/rules'], ['/api/esi', 'get', '/api/esi/rules'], ['/api/gratuity', 'get', '/api/gratuity/valuations'], ['/api/eps', 'get', '/api/eps/valuations'], @@ -226,6 +227,7 @@ const ROUTER_MOUNTS = { health: null, injuryCompensation: '/api/injury-compensation', + layoffs: '/api/layoffs', integration: '/api/integrations', labourWelfareFund: '/api/labour-welfare-fund', leaveClosure: '/api/leave-closure', diff --git a/backend/src/app.js b/backend/src/app.js index 7a6ffd8a..c557cf11 100644 --- a/backend/src/app.js +++ b/backend/src/app.js @@ -96,6 +96,14 @@ const settlementRoutes = require('./routes/settlement.routes'); // wearing three quarters of the same name. const injuryCompensationRoutes = require('./routes/injuryCompensation.routes'); +// Industrial Disputes Act, Chapters VA and VB (#1830).
