The United Food and Commercial Workers International Union wants to stop ICE immigration raids on workplaces and is filing a lawsuit in federal court to request an injunction. The Union's press release about the matter is here:

The United Food and Commercial Workers International Union (UFCW), today, sought court intervention to protect the 4th Amendment rights of all Americans and enjoin the government from illegally arresting and detaining workers including U.S. citizens and legal residents while at their workplace.

The lawsuit—filed in the U.S. District Court for the Northern District of Texas—names the U.S. Department of Homeland Security (DHS) and the Immigration and Customs Enforcement (ICE) agency as defendants. The suit calls for an injunction against the excessive, illegal and unnecessary worksite raids conducted by ICE agents.
