The world has seen a trend towards increased unionisation in the last decade, expanding beyond typical industries such as manufacturing. Unions are trying to regulate the future of work, even though employees form only one half of the employment relationship. The range of collective platforms and regimes available varies significantly between Europe and North America, notably Canada and the United States, where cultural foundations and perspectives on the matter differ widely. To what degree do collective agreements concentrate on discrimination or equality? Where are the challenges in avoiding discrimination while implementing certain working conditions and/or a framework for equality, especially regarding gender, age or union? 

Comparisons between continents could provide an interesting starting point from which to establish a better understanding of the whole concept of collective relations.
