Health Workers United has produced a strike newsletter to coincide with the upcoming strikes. Well worth reading. See: https://healthworkersunited.wordpress.com/2022/12/09/nhs-strike-newsletter-whose-strike-is-it/
Don’t forget to get your copy of their book, produced together with the ACG, Sick of it All: Work, inquiry, & struggle in the NHS. See: https://www.anarchistcommunism.org/2022/09/07/sick-of-it-all/)
