The Italian Federation of Wood, Building and Allied Workers (, FILLEA) is a trade union representing construction workers in Italy.
The union was refounded in 1944 as the Italian Federation of Building Workers, an affiliate of the Italian General Confederation of Labour. By 1954, it claimed 455,000 members, although by 1998, this had fallen to 289,553. Of those, about 70% worked in construction, and most of the remainder in wood manufacturing and processing.
