Girls hi I'm interested in such a question regarding maternity leave. I submitted an sick leave and documents on April 13th. I received a SMS on April 15th that additional documents were required. On April 15th, I collected all necessary documents and went to the GZVPP and handed them over. To this day, there has been no SMS from 1414, nor any payment. However, in the "Gzvpp" it says that further processing is required. Today, I visited the GZVPP; they know nothing about what to do next, they just say wait. Has anyone encountered such a situation? What should I do next? Where should I go?
