Recently finished the book "Rebel Cities: from the right to the city, to the urban revolution" by David Harvey.

One thing he mentions is that real labour organizing includes the unemployed, and ideally extends beyond the workplace into the communities people live, adding a geographical component to organizing.

Organizing will always help the workers who are organized, but to have a leftist labour movement, one in which the power balance is tilted in favour of the workers and is class conscious, a different type of labour organizing is required.

Edit: So to actually answer the question:

It could be (pigs for example), and it might be indirectly regressive when companies try and recoup profits through greater exploitation.

But it need not be regressive, like in my original text.
