In the last few weeks in France, Italy and elsewhere the proposal has been launched for an “immigrant workers’ strike”, intended as a reply to the recent, repeated episodes of persecution against them (an embryo of the sadly famous progroms of a not-so-distant past).
We communists do not agree.  The economic crisis, which is far from being over, as politicians and hack reporters would have it, but is in fact experiencing new and dramatic sprints forward, inflates the world of the unemployed to the utmost, gradually worsening the living conditions of the proletariat, exposing those who are still in work to exhausting régimes with the threat of losing it from one day to the next.  And it gradually affects everyone, if not today then tomorrow: workers in all sectors, of all ages, genders – and geographical origins. Meekly obeying capital’s every diktat, the disastrous practice of political and union opportunism that has developed over so many decades of betrayal and abandonment, cheating and face-changing, has progressively isolated proletarians and kept them locked in their categories, firms, areas, regional wage differentials, terms of contract, the thousand and one traps of the world of work which, in order to respond to the economic crisis, has conceived and introduced every possible kind of segmentation, dispersion, job insecurity. 
To win a victory, even if it is only an immediate one, the reply can only be to resume open and unrelenting class warfare, refusing to tolerate any separation, ghettoization, division within that enormous army that continues to swell whilst the crisis proceeds and that we call the world proletariat. To launch the slogan of an “immigrant workers’ strike” means going down the road of betrayal.  It is not a sectional strike that proletarians need today, not the thousandth segmentation within their ranks.  They need strike action that is as widespread as possible in terms of both time and place, which involves every sector of the exploited, attacked, repressed and divided proletariat.  They need to re-experience the sense of their collective strength in practice, to feel and make it felt that “an injury to one is an injury to all”, to close ranks in a single battlefront – because this is how to shake the world of capital.
