SUEPO is the acronym for Union Syndicale European Patent Office (EPO). The EPO has offices in Berlin, Munich, The Hague and Vienna. Union Syndicale therefore has four sections, one per site. About 50% of the staff at each site are members of US. SUEPO is very concerned about the working conditions of the staff working at the European Patent Office. This concerns not only salaries and pensions, but also basic rights and more general, day-to-day aspects of the working conditions of EPO staff, such as working time, workload and ergonomics.
