  • Are you up to date on important Polish labour law matters?

  • Employee monitoring in the modern business services sector

    As the modern business services market continues to experience explosive growth in Poland, it is worth keeping in mind the legal issues surrounding practices related to monitoring of employees. The line between lawful and unlawful monitoring practices is at times unclear, and issues of personal data protection also must be kept in mind.
  • Processing personal data in the BPO/SSC sector

    Personal data protection generates a large number of difficulties in the day-to-day activity of service centres. This results from the complicated processes surrounding the processing of personal data in international corporations and the unique nature of the BPO/SSC industry, but also from the restrictive requirements of Polish law regarding personal data. 
  • Common minimum wage in Germany

    New minimum wage act sets lowest hourly remuneration for workers at Euro 8.50 from 1 January 2015. This regulation will have crucial impact on undertakings from other countries providing their services in Germany. Foreign employers will have to comply with the new law and pay their employees staying in Germany at least Euro 8.50 per hour. 
  • The costs of Commercial Property Lease - Polish Law vs. Market Practice

    The practice of entering into double net or triple net lease agreements has become fairly common in the modern commercial property market in Poland. This means that a significant majority of the costs of the upkeep of the leased property are shifted to the tenant.
  • Revolution in liability towards companies under the statutory warranty

    New rules of statutory warranty bring longer deadlines and significantly alter the buyer's rights.
  • Energy Law - proposed amendments to regulations on renewable energy sources

    We are pleased to send you brief description of the main points of the bill of the Renewable Energy Sources (RES) Act, published by the Ministry of the Economy in December, 2011, and its comparison with the current RES support system.
  • Poland Arbitration 2011

    One issue under discussion is whether Poland should become a party to the Washington (ISCID) Convention. Because Poland is a party to more than 60 bilateral investment treaties (BITs) and has recently been a party to several high-profile investment arbitration proceedings, becoming a party to the ISCID Convention is discussed among practitioners, but faces strong opposition on the government side. Apart from that, another issue is whether Poland should continue to maintain BITs at all with other countries within the EU.
  • Wind energy in Poland

    The investment climate in Poland in 2009 was favourable, particularly in comparison to other European countries. Not only did the economy not give in to the crisis but it also developed at the highest pace in Europe, and Polish enterprises were able to improve the effectiveness of their business operations. The favourable investment prospects are confirmed by the fact that Poland was among the world’s top 12 most attractive direct foreign investment destinations according to the UNCTAD ranking.
  • Report on the scale of customs seizures of goods suspected of infringing intellectual property right

    Statistics in recent years show a constant increase in customs seizures of counterfeit goods. Goods seized these days by the customs authorities are not only those that are usually associated with counterfeiting, such as cosmetics, clothing and CDs/DVDs, but they also include items such as medicinal products, foodstuffs and toys. Attempts to import counterfeit goods of this type can lead to serious risks to the life and health of consumers.
