Hi I'm a tradie and my boss is sending me to do a drug test as we are going to be working for state rail. Now I don't do drugs but did when I was younger but I'm on the methadone treatment program. I will declare this and take my script but I'm worried that they will deny me because they think it's unsafe even though I've worked every day for years like this and generally dose after work. Also if they do deny me my boss will want to know why and I don't want anyone to know I'm on the program because people look at you differently. Can they tell my boss??? Please help
