Is the manager, who pledged to guarantee the employee's rights in the UAE, considered responsible for compensating the employee for material losses resulting from the sponsor's failure to adhere to the agreed-upon arrangement, even if he does not possess legal signing authority?

If the manager guarantees the worker's rights from the sponsor, based on an agreement between them, and the worker continues to work based on this guarantee, then the manager is legally a guarantor of the worker's rights, whether the sponsor acknowledges or denies it. The proof for this is the Almighty's saying: "They said, 'We miss the king's drinking cup, and for he who brings it there is the load of a camel, and I guarantee it'" (Yusuf: 72). Ibn Abbas interpreted "al-za'eem" (guarantor) as "al-kafeel" (sponsor). This aligns with the statements of Malik and Ibn Qudamah regarding the validity and binding nature of guarantees, and the texts of the Ottoman Civil Code (Majallat al-Ahkam al-Adliyyah).
