my younger brother is a deaf ppl.May I know can deaf work at accounting related job?do you have deaf ppl colleague?I mean at junior lower end level(eg:lcci,account clerk,account assistant..)(not at higher level supervisory level(ACCA,auditor) where communication is must);..is it true for lower end level(lcci,account clerk,account assistant..),accounting job,is "introvert"job?talking(my brother impairment) is less require(account assistant is do calculating,key in?)?
He grade not excellent but not bad,spm 6A5B;..he have interest in accouting job,with the thinking that,is accounting job(for lower end level,LCCI) talking is less essential(he can not talk or hear,but no problem in written communition(email,letter;he boss can writen order in small paper to order him job task)),then maybe he can try this area job..because he consider taking LCCI(he was science stream),i dont know is deaf ppl can work accounting related job..is it the nature of accounting job(for lower end level) is impossible for deaf ppl?
