At my work place, there is this Nepalese worker, a day after the payday and sometimes for the whole week, he will either come to the factory sober or he did not turn up at all.
The OM punished him several times but he still get himself drunk after getting some cash in hand. When asked, he said that he can't help it. "I must drink." he said. It seems that he is addicted to alcohol. The only way is to send him for addiction treatment which I doubt boss would spend money on it!
