Mandatory drug testing

The majority of employers have adopted mandatory random drug testing on their employees, arguing that the enormous damage caused by the pervasive use of drugs in our society carries over into the workplace. Typically the tests involve taking urine or blood samples under close observation, thereby raising questions about personal privacy as well as privacy issues regarding drug use away from the workplace that is revealed by the tests. 

Present & defend your view concerning mandatory drug tests at the workplace.

In your answer, take account of the argument that, except where safety is a clear & present danger, as in the work of pilots, police & the military, such tests are unjustified. Employera have a right to the level of performance for which they pay employees, a level typically  specified in contracts & job descriptions. When a particular employee fails to meet that level of performance, then employers will take appropriate disciplinary action based on observable behaviour. Either way, it is employee performance that is relevant in evaluating employees, not drug use per se.

What do you think?

Drugs are very dangerous so, the company does this random test trying to reduce the drug abuse. In my opinion this test is useful if the people know that they can lose their jobs because of drugs. For the privacy, I can say this is an issue that can affect the future development of our life. On the other hand, some jobs need full attention for people and property safety like a pilot; he must be fully aware because his job is  a very risky job.
