When submitting monthly claims for reimbursement of sickness absence allowances, we always encounter problems with rejection of claims due to the worker's inadequate basis. When establishing the basis for reimbursement, we repeatedly encounter problems of not getting complete information from workers at the time of recruitment (or not having it, not knowing where to get it, only bringing it from the last employer, being self-employed, etc.). An incorrect basis means that the claim is rejected and the reimbursement received is delayed. When establishing the basis, we are informed by the ZZZS clerks that, although they have the amount of the basis, they are not entitled to tell us. In some cases, the ZZZS also does not have complete information. In view of all the above, my suggestion is that, in the above-mentioned procedures, there should be proper communication between the public services and that the employer should be provided with the appropriate basis for the employee for whom a claim is being made. This could be part of the submission of a claim on e-VEM. In the hope that this initiative will fall on the right ears, I warmly welcome you.
