Notice periods sit at the exact point where two HR problems meet. One is attrition, which India has been getting better at managing. The other is backfill planning, which has quietly gotten harder even as attrition has cooled. The connection between them isn’t obvious until you look at the data side by side.
India’s overall attrition rate declined to 17.1% in 2025, down from 18.7% in 2023, according to Aon’s Annual Salary Increase and Turnover Survey 2025-26. But a falling national number hides what matters more to a hiring manager than the headline figure: which sectors are still bleeding talent and how long each exit actually takes to resolve once someone resigns.
What The Attrition Numbers Actually Show
Aon’s 2025-26 survey data breaks attrition down by sector, and the spread is wide enough that “national attrition” is close to meaningless as a planning number.
| Sector | Approximate 2025 Attrition |
| E-commerce | 28.7% |
| Professional Services | 22–26% |
| BFSI / Financial Institutions | 18–27% |
| IT Services | 19–25% |
| Engineering / Manufacturing | 12–17% |
| GCCs (Global Capability Centres) | ~12.6% |
| Metals and Mining | 8.6% |
The gap between the highest and lowest sector is over 20 percentage points, which makes a single company-wide attrition number nearly useless for planning. GCCs have also pulled off one of the sharper improvements in the market, dropping to historic lows through long-term incentive structures and skills-first retention.
TCS, Infosys, Wipro, and HCLTech still sit toward the higher end of IT attrition even as the sector average has moderated from its post-pandemic peak.
For anyone building a workforce plan, the sector number matters more than the national one. A BFSI HR head planning backfill capacity for 2026 is working against a very different reality than a manufacturing HR head, even though both will read the same 17.1% headline in the papers.
Notice Period Norms Across Roles And Sectors
Notice periods in India aren’t set by a single labour law. They come from the employment contract, read alongside state Shops and Establishments Acts and, more recently, the Industrial Relations Code, 2020, which took effect on 21 November 2025 and folded in the Industrial Disputes Act, per the Ministry of Labour and Employment’s official gazette notification.
That’s a change worth flagging for any HR compliance team still referencing the old Act by name in policy documents. Duration still tracks seniority and sector fairly predictably.
| Employment Stage / Role Level | Typical Notice Period |
| Probation (most sectors) | 15–30 days |
| Entry-level (confirmed, 0–2 years) | 30 days |
| Mid-level (2–7 years) | 30–60 days |
| Senior / specialist (IT services) | 90 days |
| CXO / leadership roles | 90–180 days |
The IT services sector is the clearest case of a long, rigid notice culture. Original research from Analytics India Magazine found that almost 1 in 3 IT roles in India carries a full 90-day notice period, the highest share of any professional or skilled job category in India Inc. Major players like TCS, Infosys, Wipro, HCLTech, and Tech Mahindra typically apply 90 days for experienced employees.
The split follows a consistent logic:
- Services firms run long. Product companies and GCCs tend to run shorter, at 30 to 60 days, which is one reason talent flows so easily from services firms toward product companies whenever hiring picks up.
- BFSI mirrors IT for senior grades. Officer and manager grades often sit at 90 days, while insurance arms of the same sector tend to run 30 to 60 days.
Startups and D2C companies deliberately keep notice periods short, sometimes 15 to 30 days even after confirmation, and treat that as a hiring lever against larger competitors with longer notice cultures.
Why Long Notice Periods Don’t Behave The Way They’re Designed To
The stated purpose of a long notice period is continuity. It buys the employer time to find a replacement, transfer knowledge, and protect client relationships, particularly in IT services, where contracts with clients sometimes specify that key personnel stay on a project for a defined period after resignation.
In practice, the length works against that intent more often than it serves it:
- Offer dropout climbs with notice length. A three-month gap between offer acceptance and joining date leaves enormous room for counteroffers, competing offers, or a simple change of mind. Analytics India Magazine’s research on notice periods found that almost 1 in 3 IT roles carries the full 90-day term, which is exactly the window where candidates have the most time to be pulled away before joining. For senior positions hired through traditional channels, offer acceptance in India runs at roughly 55 to 65%.
- Engagement during notice tends to fall, not hold steady. An employee serving out 90 days after deciding to leave isn’t the same contributor they were a month earlier. HR practitioners describe this stretch as a period where productivity and engagement visibly drop, even though the person is still logging in and nominally responsible for their targets.
None of this means long notice periods achieve nothing. They buy real time for knowledge transfer in specialist and client-facing roles. But longer doesn’t automatically mean smoother, especially when the same length is quietly working against retention in the weeks before someone’s actual last day.
The Backfill Math HR Teams Often Get Wrong
Backfill planning usually starts from time-to-hire. That’s the wrong starting point in India, because it ignores the notice period sitting on the other side of an accepted offer.
The average time-to-hire in India runs roughly 35 to 45 days from an approved requisition to an accepted offer. That’s the number most dashboards track. It also varies sharply by sector:
| Sector / Role | Typical Time-to-Hire |
| Retail and e-commerce | 14–20 days |
| General mid-level roles | 35–45 days |
| BFSI | ~44 days |
| Senior AI/ML or cybersecurity | 50–70 days |
What most dashboards miss is the offer-to-start gap. Roughly one in three IT roles in India carries a full 90-day notice period. Add that to a 35- to 45-day time-to-hire, and the real distance between “role opens” and “seat filled” can run past four months for a senior technical hire.
A simple way to see the difference:
| Metric | Duration |
| Time-to-hire only (requisition to accepted offer) | 35–45 days |
| Real fill timeline, 30-day notice hire (requisition to first day) | 65–75 days |
| Real fill timeline, 90-day notice hire (requisition to first day) | 125–135 days |
That gap is completely predictable once it’s tracked as its own number. Most HR teams don’t track it separately, which is exactly why the 90-day wait keeps arriving as a surprise instead of something staffed around from the start.
What Backfill Planning Needs To Account For
A 125-to-135-day fill timeline isn’t a number most workforce plans are built around. Closing that gap starts with how HR tracks and sequences backfill work.
- Track offer-to-start as a distinct metric. Don’t fold it into time-to-hire. The requisition doesn’t close when an offer is accepted; it closes when the person is at their desk. Reporting the earlier number as the real one understates the operational gap by months in notice-heavy sectors.
- Segment backfill urgency by sector attrition, not company-wide attrition. A company running a blended 17% attrition rate might have a BFSI vertical at 26% and a manufacturing vertical at 13%. One company-wide backfill buffer treats both the same way, leaving BFSI chronically understaffed while manufacturing carries slack it doesn’t need.
- Build pipeline depth before the resignation, not after. The deeper the bench of viable candidates already in conversation, the less any single 90-day notice period can stall a critical hire. Waiting for a resignation letter before opening a search adds the full notice-period gap to the hiring timeline instead of running it in parallel.
- Separate the knowledge-transfer function of notice from its retention function. Long notice periods were partly designed as a soft retention tool, meant to discourage impulsive job-hopping by making exits slower and costlier. The data above suggests they don’t do that job especially well. Treating notice primarily as a structured handover window, with knowledge-transfer documentation built in from day one, tends to produce a cleaner exit than treating it as a leash.
- Watch the 12 to 24 month tenure band separately from overall attrition. Exit-interview data from AceNgage identifies this window as the highest-risk tenure band across sectors, producing the largest volume of exits and the highest share of preventable ones. Flagging this cohort early, through structured stay interviews around the 9-month mark, buys HR a 60- to 90-day window to intervene before a resignation and a 90-day notice period stack on top of each other.
In The End…
Attrition in India is trending down. Notice periods, for the roles where it matters most, are not trending shorter. That mismatch is the real planning problem, not the headline attrition number itself. A company that reads 17.1% and assumes it has room to relax on backfill capacity is misreading what the figure actually says about its own risk, particularly if its workforce sits concentrated in IT services, BFSI, or e-commerce.
The practical fix isn’t lobbying to shorten notice periods, which remain a matter of contract and show no sign of a coordinated shift toward the shorter norms seen in the US, UK, or Singapore. It’s treating the offer-to-start gap as a metric worth tracking on its own, building sector-specific attrition buffers rather than a single company-wide one, and starting the next search before the current resignation letter lands.
None of that requires new legal ground. It just requires HR to stop measuring the parts of the hiring funnel that are easy to measure and start measuring the one that actually decides whether a seat stays empty for two months or five.
FAQs
What is the average notice period in India?
Notice periods in India vary by seniority and sector. Probation typically runs 15 to 30 days, confirmed entry-level roles carry 30 days, mid-level roles run 30 to 60 days, and senior IT or leadership roles often reach 90 to 180 days.
Why do IT companies have 90-day notice periods?
IT services firms use long notice periods to protect client contracts, allow knowledge transfer, and cover project continuity. Almost 1 in 3 IT roles in India carries a full 90-day term, the highest share of any skilled job category, according to Analytics India Magazine.
What is the current attrition rate in India?
India’s overall attrition rate fell to 17.1% in 2025, down from 18.7% in 2023, per Aon’s Annual Salary Increase and Turnover Survey 2025-26. Sector figures range from around 8.6% in metals and mining to 28.7% in e-commerce.
What is the difference between time-to-hire and offer-to-start?
Time-to-hire measures the gap from an approved requisition to an accepted offer, roughly 35 to 45 days in India. Offer-to-start captures the notice period a new hire serves before joining. For a 90-day notice hire, the real fill timeline can stretch to 125 to 135 days.
How can HR teams improve backfill planning?
HR teams should track offer-to-start as a separate metric, segment backfill urgency by sector attrition rather than a company-wide figure, build pipeline depth before resignations land, and monitor the 12 to 24 month tenure band, which produces the highest share of preventable exits.
Did the Industrial Relations Code change notice period rules?
The Industrial Relations Code, 2020 took effect on 21 November 2025 and folded in the Industrial Disputes Act, per the Ministry of Labour and Employment. Notice periods still come from the employment contract read alongside state Shops and Establishments Acts.
