Girls, hello ?? I have a question, I'm going on maternity leave. I work as a teacher at a college, and my salary is good accordingly. I went to the Pension Fund with documents, and they told me that the accountant needs to re-calculate social contributions. Because my social contributions exceed the allowed amount, although the accountant sends everything by fact. Is this legal?
