Under which conditions can an employer terminate...

It should be noted that the employer’s refusal to issue an employment contract for you is considered a violation against the employer, and you may file a complaint against him at the Labor Office for his refusal to issue an employment contract for you. Regarding your termination from work on Facebook, this matter is not permissible and you may go to your workplace and if the employer refuses to let you work on the grounds of dismissal, this is considered arbitrary dismissal and you may file a complaint against him at the Labor Office regarding that arbitrary dismissal, and the employer will be summoned and asked about your complaint and then your complaint will be referred to the court to judge you for all your financial dues resulting from the arbitrary dismissal.
