Make your work a form of protest.
Do you have some flexibility with where or when you work?
Some ideas: Organize a "work-in" somewhere like your city hall, capitol, ICE building, court, town square, etc. Bring signs and flyers.
Do you work onsite somewhere but have a lunch break?
Some ideas: Organize a lunchtime demonstration with your coworkers outside or a reading or action group.
You're a homemaker, stay at home parent or caregiver?
Some ideas: Have sign making parties with the kids, build collectives to help each other with childcare and collectivize tasks, have phone call action hours where you take turns caring for the kids while some of you call your elected officials.
Have flexibility with what you can wear?
Some ideas: wear your support as tshirts, pins, hats, etc.
Have any kind of job?
Some ideas: talk with your coworkers, figure out actions you can take within your organization to protect your community from the trump regime, create resistance in your organization, unionize.
