Evening everyone,in 2011 I abandoned a task at Sibanye Stillwater because of clinical complications,i 2013 I proceeded to do my Medical Exit,I got recruited by Anglo in 2015 unti last year December.I acknowledged a proposition I was unable to afford to ignore at Sibanye again.I did my medicals,screening and all the documentation for work is done simply left to do a clock card.So while I occupied with the clock card,the framework says I can't be re employed,remember I surrendered at Anglo.Is that fair after to make somebody his/her occupation after that not re-enlist him or her?And interaction would I be able to follow to battle this?
