The agency versus in-house question in Türkiye is not a global TA debate played out in a local setting. It has its own legal architecture, its own actors, and patterns specific to each sector. Understanding the framework — and what the country's largest employers actually do — prevents both the liability risks of informal arrangements and the dependency traps of agency-heavy models.
The Legal Foundation: Geçici İş İlişkisi
The framework that makes most external workforce arrangements in Türkiye possible is geçici iş ilişkisi — the temporary employment relationship established under İş Kanunu (Labor Law No. 4857, significantly amended in 2016). Under this model, a licensed özel istihdam bürosu (private employment agency) is the legal employer: it registers workers with SGK, processes payroll, handles severance calculations, and bears the compliance burden. The client organization directs the work.
For frontline employers, this is the only legally compliant way to use temporary or leased labor in Türkiye. Employers who use informal subcontracting arrangements to avoid SGK contributions face serious liability under Article 2 of the Labor Law (muvazaa/sham subcontracting), which courts have increasingly enforced.
Compliance signal: An agency or subcontractor that offers dramatically lower costs than the market rate is almost always cutting corners on SGK contributions. That cost advantage transfers to the client as legal liability. Vetting a partner's SGK compliance record before signing is not optional — it is risk management. |
The Agencies That Operate in This Market
Türkiye has a defined set of players in the licensed agency space:
Agency | Best for | Key note |
Adecco Turkey | Production line temp staffing, automotive & electronics, peak logistics | Most deeply embedded global agency in Türkiye's manufacturing sector. Strong relationships with industrial zones in Kocaeli, Bursa, and Gebze. Used by Ford Otosan and Şişecam for geçici iş ilişkisi headcount. |
Manpower Turkey (ManpowerGroup) | High-volume blue-collar, retail distribution, airport ops, finance ops | Broad national coverage. Used by TAV Havalımanları for non-permanent ground ops headcount. Their RPO arm (Experis) handles white-collar placements separately. |
Randstad Turkey | Retail, FMCG, administrative, seasonal surge | Strong in retail and consumer goods. Used by CarrefourSA and Migros for seasonal and distribution center headcount. Their on-site management model suits high-turnover environments. |
Human Group | Factory floor, logistics hubs, Kocaeli / Eskişehir / Bursa / Gebze | Turkish-founded firm with deep local roots in the Marmara industrial corridor. Consistently cited by hiring managers in automotive and logistics as the faster, more responsive option for urgent regional needs. |
Grafton Turkey | Last-mile logistics, courier surge, warehousing | Active in logistics and courier surge hiring — relevant for Yurtiçi Kargo and Aras Kargo Ramadan and Q4 ramp-ups. Acts as legal employer under geçici iş ilişkisi. |
İŞKUR | Regional cities, investment-zone hiring, vocational referrals | Not a private agency, but worth treating as one. Free job postings, candidate databases in every province, SGK subsidy incentives for Teşvik Bölgesi hiring. ~79,000 active openings as of April 2026. Vestel's Manisa campus is the best-known example of a large employer that has built İŞKUR into its standard pipeline. |
What Türkiye's Largest Employers Actually Do
Employer | Dominant model | Türkiye-specific reality |
BİM / A101 / ŞOK | Fully in-house | Scale makes agency dependency impractical. Store managers are the de facto recruiters — TA's real job is building the tools and processes they can actually use. |
Turkish Airlines | In-house + specialist | Cabin crew hiring is managed directly and is brand-sensitive. Ground ops uses agencies for seasonal surge at secondary hubs. Language assessment is a genuine bottleneck. |
TAV Havalımanları | In-house + temp staffing | Airport ops require SGK compliance from day one. Adecco and Manpower Turkey are the main temp partners for non-permanent headcount. |
Yurtiçi / Aras Kargo | Mixed, agency-heavy at peak | Driver shortage is structural. Courier surge for Ramadan and Q4 is handled via leasing. Retention after surge is the chronic pain point. |
Limak / Cengiz İnşaat | Subcontractor networks | Project labor is mobilized through trusted alt-yüklenici (subcontractor) relationships built over decades. Central TA sets standards; subcontractors source. The model works until a project is in a new geography. |
Ford Otosan / Şişecam | In-house + workforce leasing | Flex production headcount managed via geçici iş ilişkisi. Partners: Adecco Turkey, Manpower Turkey. Vocational school pipelines are the long-term anchor. |
Vestel Elektronik | In-house + İŞKUR pipeline | Manisa campus hiring is tightly integrated with the local meslek lisesi network. İŞKUR provides a meaningful flow of pre-registered candidates. |
Concentrix Turkey | Structured RPO / BPO model | Runs a more formalized TA operation than most domestic employers — with structured assessment, language screening, and centralized ATS. Agency role is limited to specific language or overflow capacity. |
The Hybrid Model That Works in Türkiye
The hybrid model that performs best in Türkiye is shaped by two market-specific facts: SGK compliance is binary and non-negotiable — it defines which external arrangements are viable and which create liability. And regional labor markets in Anatolia, the Black Sea coast, and Eastern Turkey are thin enough that the choice of partner matters more than the choice of model.
The strongest in-house TA operations tend to own three things permanently: the WhatsApp funnel and candidate experience, the hiring manager relationship and process alignment, and the data — the ATS records, the 30-day retention rates by source, the pipeline benchmarks by city. Everything else can flex.
Agencies and subcontractors that plug into that infrastructure — using the employer's pre-qualification criteria, receiving the employer's job briefing materials, reporting into the same tracking system — behave like extensions of the TA team. Those that operate in parallel, with their own processes and their own data, produce inconsistent results regardless of their reputation.
Test for any external partner: Will they operate inside your funnel — using your prescreen criteria, your job messaging, your ATS fields — or will they run a parallel process and deliver completed candidates at the end? The first model compounds. The second creates permanent dependency. |
A Türkiye-Specific Consideration: The Favoritism Problem
Türkiye's HR and TA community is small and densely connected. Recruiters move between the same set of large employers. Hiring managers have personal networks that overlap with candidate pools. In this environment, informal influence over hiring decisions — whether through family ties, personal relationships, or internal political pressure — is a recognized concern.
One practical response that has emerged in the market: companies deliberately route certain hires through external headhunters or agencies specifically to create distance between the decision and internal networks. Structured, criteria-based screening tools serve a similar function. When every candidate passes through the same automated pre-screen, answers the same questions, and is assessed against the same knockout criteria, the selection outcome is documentable and consistent. In Türkiye's hiring environment, this is not just an efficiency argument — it is increasingly a governance argument.
