You have to file a complaint at the labor office about what happened to you, as you are forced to resign. This is considered an arbitrary dismissal. Knowing that, according to the labor law, you are entitled to a sick leave. The case could be resolved amicably by the labor office or it shall be referred to the labor court and you do not have to sign the resignation.
A worker who contracts illness after completing three months, following the probationary period, in the continuous service of an employer shall be entitled to a sick leave not exceeding 90 days, successive or otherwise, in respect of each year of service, to be calculated as follows.
• The first 15 days: with full pay.
• The next 30 days: with half pay.
• Any subsequent periods: without pay.
No wage shall be payable for sick leave if the illness is the direct result of the worker's misconduct (such as consumption of alcohol or narcotic drugs).
