You just do not get it do you?

If someone is unable to do their job properly due to their recreational habits, then it is the business of the employer......working in a stockroom away from the general public still has safety issues. The general public are not the only ones who can be affected by someones inability to spot risks.
An employer has to make sure that all his workers are safe....and if the person who s still hungover from Alcohol/spliffs causes an accident because they are incapacitated from their habit.....then it is of concern to the employer.

If you like to partake of recreational drugs, then you have a responsibility to make sure that they are out of your system before you are due back at work.

Or is this just another thread where you stir the pot?
Pose a question, but if you do not like the answers you fudge the issues.

If I were still of working age(which thankfully, I am not)......I would have absolutely no qualms about my employer testing me for alcohol or drugs.
