Say you’re a teacher, then need to get surat from Kementerian Pelajaran Malaysia (KPM)

If you’re JKR engineer, need surat from Kementerian Kerja Raya

If you’re a nurse, need surat from Kementerian Kesihatan Malaysia (KKM)

And the lists go on.

If you keja kilang swasta, i think Ministry of International Trade and Industry (MITI), not sure not valid anymore?
