As it has been said uncountable times, labor conditions and progress, like all meaningful improvements for worker, are achieved through demonstrations. These demonstrations are often recipients of violence from the state or state-sanctioned actors.
By joining/forming relationships with organizations in your community with aligned beliefs and goals, outside of your workplace, you can draw support, and provide support, for others. Many of these groups have experience with demonstrating, counter-demonstrating and protecting their comrades when things get physical.
Providing for members of your community, whether ideologically aligned or not, with necessities (food, clothing, blankets, toiletries, etc), monetary relief in tough situations, volunteering and offering support for anything that can aid those in need, prison abolition, solidarity with tenets organizations, etc. are invaluable as forms of spreading our values, in addition to helping those in need.
Unionization, strikes, support strikes outside of your own workplace and industry, are all of the utmost importance, but we can’t stop there. We’re all workers, 99.9% of your community are workers.
The capitalists, their PR wings, politicians on their payrolls, and corporate media have worked a number on us, especially over the last 50+ years. “Why should a ‘burger flipper’ get $15/hr when I, a (insert woefully underpaid trade worker) makes $16/hr?!”, and other variations of that sentiment are doing the work for our exploiters. Support your fellow workers, regardless of their industry or job.
