Fascism tends to have these attributes: * dictatorial power
* totalitarian one party state
* embrace of political violence as a means to silence opposition
* strong opposition to Marxism, liberalism, conservatism
* radical nationalism
* nationalist economic policy through protectionist schemes
Funny, but if you just erase the word "Marxism" then you also have something which resembles the Soviet Union under Stalin. It also fits a lot of historical communist regimes, though the nationalism is disguised or submerged as "worker solidarity." However in times of war or crisis, they generally bang the nationalist drum as hard as anyone else. A "nationalist economic policy through protectionist schemes" is just meddling against markets and central planning by another name.
National Socialism and Fascism are identified as "right," but this is primarily through the application of nationalism, conquest, and opposition to communism. Look under those fig leafs, and you find something very different.
National Socialism and Fascists consistently implemented socialist policies. Under National Socialism, control by the state was so complete, the private ownership meant nothing. Property owners were called Betriebsfurhrer -- basically shop managers enacting state policy. What was made, who it was sold to, how much was charged, and how much the workers were paid were largely determined by the government. National Socialism was strongly against liberal democracy. (Liberalism in the 19th century Classical Liberal sense, which in 2019 is labeled "conservatism" in the US.) They were also openly against free markets, multi-party democratic government, freedom of speech, and other individual human rights. Mussolini started out as a Socialist, and at one point, he literally styled himself, "The Lenin of Italy." Also, many of the essentially socialist policies of National Socialist Germany in the 1930's garnered praise from American progressives.

What about a group of employees collectively organizing and protesting non-violently against an internal board at a privatized company is exactly fascist?
The collectivism is a shared attribute of Fascism. Also, as observed in a different comment, if they are suppressing dissent and speech in their own ranks and using pressure tactics to keep their own ranks in line, then this is another shared attribute.
