i took on a guy this time last year who said he was a 3rd year but i knew after 3 days if anything he was a 1st year.i wanted to see this guy progress so i sent him to fas were he failed 5 of his 9 exams.last week he asked me for a raise and i gave him one and now i regret it as he cant produce that labour for the amount of salary he is being paid should i let him go? or give him the benefit of the doubt any advice appreciated
