  • What are the differences between hiring an employee on an employment contract and B2B?

    • B2B and employment contracts primarily differ regarding the body of law to which the parties of a contract are subject. For an employment contract, it is the Polish Labor Code, and for B2B contracts it is the Civil Code.

      The tax and social security payment liability is one of the more significant differences. The employer covers these costs for an employee under an employment contract. In the case of a B2B contract, the costs are borne by the contractor. 

      In addition, an employee on an employment contract is provided with paid vacation (20 or 26 days depending on tenure), paid sick leave, and additional days off for occasional special situations (funerals, births, etc.). An individual on a B2B contract may be provided with paid vacation under the terms of a gentleman's agreement with the employer.

      Both contracts also differ in their notice periods: for an employment contract, the notice period ranges from 2 weeks to 3 months, while for a B2B contract, it is flexible, but usually 1 month.
  • How long does it take you to deliver a specialist/a team of specialists?

    • It depends upon the role, its complexity, and technical requirements. Usually, it takes us between 5 and 15 working days to fill a vacancy.
  • How do Link Group’s contractors report their working hours?

    • It works both ways: Contractors monitor and report their hours directly in the client's ATS system, where at the end of each month managers approve them or conduct the hourly reports in their Spreadsheets (also approved by  managers).
