What is the term for the action by unionized workers to demand better conditions or pay by assembling near their employer's entrance?

The term that describes the action by unionized workers assembling near their employer's entrance to demand better conditions or pay is picketing. Picketing typically involves workers holding signs and gathering outside the workplace to inform the public and draw attention to their cause, often as part of a labor dispute. This form of collective action aims to raise awareness and put pressure on the employer by showing solidarity among the workers and attracting public support for their demands. Picketing is distinct from striking, which involves workers refusing to work, and from protesting or demonstrating, which can take place in various contexts and locations beyond the employer's premises.
