My suggestion is to pay from gross salary/pension... instead of supplementary health insurance, because it will be less noticeable to employees, and net pay correspondingly less. But we would pay depending on the level of gross salary - 2 percent. Simplistically, health care contributions could only be increased by 2 percent, but should not be an additional burden on business. Others, who now have compulsory supplementary insurance, would be charged a flat rate of €20....
 
A lower contribution limit of €20 could be set.
