The Union of Transport Workers (German: Gewerkschaft des Verkehrspersonals, SEV) is a trade union in Switzerland.
Many transport workers were involved in the 1918 Swiss general strike, and this inspired members of various small unions to found a national union for railway workers.
While it had a centralised political leadership, under Robert Bratschi, linked with the Social Democratic Party and based in Bern, many of its sectoral groups operated with a high degree of autonomy in industrial matters.
In 1995, it was renamed as the Swiss Railway and Transport Staff Association, to emphasise the role of these other workers, then in 2009 it became the "Union of Transport Workers".
