16. Rajah Management (RM), the authorized local placement agency of Sultan Group (SG), posted a job listing for project manager based in Qatar. Silang applied for the position. After RM forwarded the documents of Silang to SG for the processing of her work visa, SG sent a tourist visa notice instead of a work visa. Six months into her two-year contract, Silang was repatriated by SG with instructions to apply anew for deployment under a work visa. RM directed Silang to undergo a pre-employment medical examination. When it was discovered that she has uncontrolled diabetes, SG terminated her employment. Thus, Silang filed a complaint for illegal dismissal against SG and RM. SG argued that the disease of Silang was a valid cause for dismissal. Is the contention of SG correct? Discuss.
