A picket line is a gathering of union members and supporters who meet up outside their place of work, and will typically walk and chant. A picket line is public expression by striking workers of their dispute, which conveys a request for other workers and community members to join them in solidarity. We can increase the impact of a strike by encouraging non-postdoc/ARSs colleagues to not cross the line, to join us on the line, and to avoid activities that weaken our decision to withhold our labor.
