As you might know already, we met some drug in the plant and we also conducted the test with risky group in that area.
To prevent and practice as same as last time, I would ask cooperation from your side to inform to your services provider who control the truck driver,
Please inform them to conduct the test and send the certificate of each one to HR as soon as possible.
Currently every day we start the investigation and monitoring with this group, we found some hint.
Let me know or you talk with K.Chantawat when you want to get more information.
