Bad treatment towards their honest and reliable former employees.

My husband was employed by Small Enterprise Foundation in 2020, His name is Lucky Solly Mahlo. ID N0. 7903205475088. He was maltreated by his branch manager and resigned towards the end of 2020. Later we heard that the manager lost his job. My husband now want to be reinstated to his former job and we called the organization requesting them and we also wrote an email and they responded that they no longer reinstate former employees. But they have to take positive measures of weather the employees stole anything from the company or he just resigned because of maltreatment.
