I ended a persons job because of a positive drug test. He had drugs in his system, and was tested after he was injured on the job. He claims he partied over Thanksgiving. The level of the drug was higher and the doctor said that it had to have been ingested in the last 24 hours.
The accident could have been a lot more serious had not another employee been paying attention and stopped the line.
I said it earlier and I will say it again - I would rather fire 100 people than have to sit across from 1 persons family and say I am sorry for this accident - or worse.
