Law enforcement officers were seen responding to a protest outside Kaiser Los Angeles Medical Center in the East Hollywood area, led by a union which has accused the company of unfair labor conditions.

The union reports that the strike has left thousands of Kaiser patients facing long waits and canceled appointments. Mediation talks could begin as early as February 17.

Kaiser’s public comments about the negotiations have been strident and consistent. The health giant’s most recent update, emailed to Capital & Main by a spokesperson, reiterated long-established talking points that the union is exacerbating the problem by not accepting Kaiser’s terms.
