Why Sii Poland advantages of working with us

The effectiveness of our recruitment services is guaranteed by 70 recruiters, 100 line and resource managers, who with the use of dedicated IT tools increase the number of CVs by 400 each month. Apart from the direct search, we cooperate with leading job boards, universities, professional associations as well as organize employer branding activities – all in an effort to identify and promote the best on the market.

The added value of supplementing the project teams with Sii specialists is the Administrative and Back Office support which deals with all the tax and employment responsibilities, from negotiating and signing contracts, through managing payroll taxes, delegations, employee relocation procedures to providing work related incentives. We have the expertise to handle the processes with a quick turnaround allowing our clients to focus on their core business.

We provide flexibility to the Clients as they can resign or not renew PO for their subcontractors at any time, e.g., when budget must be decreased or project ends. Also, it is easier and quicker to terminate the contract with Sii, decrease capacity and FTEs, than with permanent employees, as the Clients face no risk of paying remuneration packages, neglecting the notice period or dealing with bad PR and lawsuits. Moreover, with subcontractors there are no trade unions and HR problems. Customers do not have to manage salary policy and employees' complains – everything is managed by Sii. In other words, Sii subcontractors are easier to manage and by this they bring flexibility to our Customers.

We assume full responsibility for the contractor, freeing our clients from all the obligations employers have towards their headcount, such as: dealing with employees' complaints, labour unions, attrition rate and dismissals. In other words, we manage all the employment-related risks for the client.
