please I need the answers to be according to the Saudi labor code ..

Ahmad is hired by SAMBA bank on January 1, 2018 as new hire/trainee. He passes the 90-day (3 months) probationary period. On April 10, 2018, he is called to his manager's office and is told he is fired and no reason is given, he does not have a written employment contract. He files a case with the labor board. SAMBA bank did not pay Ahmed for his last salary.

1- What specific complaints could Ahmed bring for violation of the labor code? (hint: a) wrongful termination; there are at least 2 to 3 others.

2- What powers does the Labor inspector have over the case

And what can he order?

3- Since there was no written employment contract, what document now becomes the labor contract?

4- At the first hearing, the representative for SAMBA refuses to appear before the labor board. What types of actions can the Labor Board bring against SAMBA bank?

5- if the oral agreement between Ahmad and SAMBA was for 1 year contract, what else could the labor inspector order in favor of Ahmad?
