Is it permissible to deal with an insurance company to which the syndicate and employees pay annual premiums in exchange for compensation for death or total or partial disability, knowing that nothing is disbursed to the employee if his service ends without injury?

The ruling on what you mentioned depends on the type of insurance: if it is cooperative and takaful, then there is no harm in participating in it and benefiting from it. However, if it is commercial insurance, which is forbidden, then it is not permissible to subscribe to it.
