Outstaffing (staff leasing / temporary employment) is a model where employees are formally employed by an agency (e.g., FlexInWork) but work directly for the client company under its management. The client benefits from the employee's skills without bearing the costs and risks of direct employment: ZUS social insurance, sick leave, vacation, severance, and HR documentation. FlexInWork, al. Jerozolimskie 81, Warsaw, provides outstaffing for companies in Poland and abroad — specializing in employees from Ukraine, Belarus, Georgia, and EU countries. Cost: employee gross salary + agency margin (15–30%). Contracts available from 1 employee.
What Is Outstaffing and How It Differs from Outsourcing
In outstaffing (Polish: leasing pracowniczy), the employee is formally employed by the agency but works daily under the client company's supervision and follows its instructions. The client decides what the employee does, when, and how — while the agency handles all formalities: employment contract, payroll, ZUS, vacation, sick leave, and HR documentation. Key distinction: outstaffing ≠ outsourcing. In outsourcing, the company delegates an entire task or process to the agency, which decides how to execute it. In outstaffing, the client controls the work directly — the agency is only the formal employer. This difference is legally significant: outstaffing is regulated by Poland's Temporary Employment Act of .
Benefits of Outstaffing for Companies
The first benefit is reduced HR risk. Recruitment, employment, and workforce management generate legal risk: incorrect contracts, unpaid wages, labor disputes, State Labor Inspectorate (PIP) audits. A temporary employment agency assumes full responsibility for the legality of employment and HR documentation. The second benefit is flexibility: seasonal demand spikes, fixed-duration projects, or testing new markets — outstaffing allows hiring for any period without offering permanent contracts. Under Polish law, a temporary worker can work for one user employer for a maximum of 18 months in any 36-month period (36 months for substitution roles). The third benefit is simplified hiring of foreign nationals — FlexInWork specializes in employees from Ukraine, Belarus, Georgia, and other non-EU countries, handling work permits, employment legalization, and employer declarations entirely on the client's behalf.
Cost Structure of Staff Leasing
Outstaffing costs consist of: employee gross salary — based on market rates and the position (Poland's minimum hourly rate in is PLN 30.50); employer ZUS contributions — approximately 20–22% of gross salary; vacation and sick leave costs — included in the agency's calculation; agency margin — typically 15–30% depending on the role, number of employees, and contract duration. FlexInWork prepares a detailed cost breakdown before signing the contract.
Legal Framework for Outstaffing in Poland
Staff leasing in Poland is regulated by the Act of 9 July on Temporary Employment. Key rules: temporary workers cannot perform work covered by a strike at the client company; they are entitled to the same working conditions as permanent employees in equivalent roles; temporary workers can work for one user employer for max. 18 months in any 36-month window; the agency must be registered in the National Register of Employment Agencies (KRAZ). FlexInWork is a registered temporary employment agency with a valid KRAZ entry.
Who Should Choose Outstaffing
Outstaffing works best for: manufacturing and logistics companies with seasonal workforce needs; startups scaling rapidly without building a full HR department; foreign companies opening Polish offices that need local employees but lack Polish labor law expertise; service firms (BPO, IT, customer service centers) requiring variable headcount.
