Worst company ever - Home Care Worker Help at Home Employee Review

After 4 years, hours were cut. Found alternative employment and left a month notice. Kept 1 client that was 100. Fired for inability to attend meetings. Filed a grievance with union. Was told I would be contacted by mail and phone of next steps. Union did nothing. Never heard anything from anyone. Paid union dues for over 4 years and they never had my back.
