Unpaid sick leave

<p>I was off sick for some time and i had exhausted my sick leave and they did not offer me any risk pool or special leve or other options as they would normally to other employees, i have been waiting for them since 2015 for my 6 months payment for that time. I feel like i was treated unfairly because that is not the procedure they normally follow other employees, can please someone assist me with this</p>
