商业秘密能够给权利人带来巨大的经济价值或竞争优势,因此要加强对商业秘密的保护,尤其是要加强对雇佣关系中的商业秘密的保护。在雇佣关系中,商业秘密权的保护与

The 1990s began with unprecedented market conditions for labour: unemployment rates were reaching their highest level in over 50 years, participation in the labour market had fallen to historically low levels and net emigration was widespread across all occupations. It seemed that things could only get better. While some did benefit from the limited growth that took place in the nineties, many did not. The greater inequality generated during the 1980s was fanned by the deregulation of the labour market and remained undiminished throughout the following decade. The marked reduction in manufacturing employment in the 1980s continued into the early 1990s negatively impacting Maori and Pacific Island men and women in particular. Increasingly post‐secondary school education became necessary to gain entry into regular work and those with little formal education and few work skills fell further down the queue. These changes are closely allied to the processes of globalisation which is already exercising considerable influence on the employment opportunities of New Zealanders. 相似文献

This paper examines some of the socio‐demographic changes which have occurred in the Pacific‐descent population in New Zealand in the last decade. It examines significant shifts which have occurred in the social and economic characteristics of overseas and locally‐born sub‐populations and identifies some of the factors which have produced these. The chapter points to the growing internal socio‐demographic diversity within the Pacific population and argues that we may need to think about this population in different ways in the near future. 相似文献
