First of all, the legal person of the work unit does not need to bear the obligation and compulsory guarantee responsibility to the applicant, so it is not illegal or illegal for the legal person of the work unit to do so.
Secondly, in the workplace, applying for provident fund is generally regarded as company welfare. Although there are five insurances and one gold policy support, the workplace is obliged to pay five insurances and one gold (not all companies will pay), but it is not obliged to apply for provident fund.
Therefore, the applicant's complaint about the legal person of the work unit is actually of little significance, but it will make the relationship between the two sides more tense.
Expert opinion: It is suggested to negotiate with the legal person of the work unit in a friendly way.
