Speaking as the president of a company, this is an interesting read. We require pre-employment drug screens, and a drug test whenever there is an accident or incident. Our company is large and we have everything from manufacturing facilities with machining and fabrication to sales people traveling around the world.
I do not mind an employee who RESPONSIBLY does whatever he does on his own time, and leaves it at home when he gets into work, but unfortunately not everyone who partakes (and I am not just talking about marijuana) is as responsible as everyone on talkbass claim, who are always in control. Also understand that for a lot of employers, it is not our decision to do to do this testing, it is required of us by those that are insuring and underwriting all of our business. While I respect your decision to say no, please respect my position that providing jobs and income for 350 people is more important to me. To be able to provide those jobs, I have to adhere to the requirements of those that make it possible. You have the right to say no, and I support it, but I also have the right to terminate. Please know that these rules apply to me also. I am not immune.
If you have a stupid moment at home, that is on you but when it happens at work I have to deal with potential workmans comp, lawsuits, potential injury to other people, damage to property, damage to product, delivery issues, etc. Even a lack of judgement regarding intellectual property can get your company in a very bad spot.
I have sales people who are on the road for weeks at a time in company vehicles we insure, or renting cars the company is responsible for when they are rented, and staying in hotels than connect back to our company, and transporting customers, clients and others that are kind of important to the company. Anytime an accident or incident happens, lawyers are ALWAYS involved. We have to protect ourselves and our employees. If you can't stay clean long enough to pass a drug test you should know is coming for a new job, why should I trust you to stay clean for weeks on end when you are representing the company ? If you have an accident or incident and there are drugs in your system even alcohol, realize it will cost you your job. Alcohol related incidents are among the most common we see.
