I don't want to give too much info here, but I have a job that involves lone working with individuals in their homes. There is generally a contract in place with the individual around particular behaviours to minimise risk to us as employees. So, for example, if the individual were drinking or under the influence of drugs, we would leave the premises.
In the case of one particular individual, there has always been a pervasive smell of cannabis around the house, but it's being used by another member of the household who has no contract with us. On one occasion, I could smell it as soon as I opened my car door, at the bottom of the drive. At that point I wondered if someone might actually be growing cannabis in the house, but didn't see anything in the areas of the house that I access.
The individual that I am visiting is vulnerable and unable to communicate if something is wrong.
I have communicated the situation back to management, but they say there's nothing to be done about it.
I guess my question is, is it ok for employees to be in a position where they lone work in an environment where someone is actively using drugs?
