Polygraph testing can be used in any business under specific investigative circumstances, as a proactive measure in maintaining a trustworthy work force, or as part of the employment process to ensure employing the right personnel into key positions.
Using Polygraph Tests Prior to Employment
The initial interview process for employment is greatly enhanced by the use of polygraph testing, where the candidate’s character, integrity and reliability can be determined. The polygraph process allows for any past indiscretions to be brought to light which cannot be done through the regular pre-employment checks that can be done. Pre-employment tests can include questions regarding substance use, theft from prior employers, undetected criminal activity as well as syndicate involvement. Companies where staff have access to proprietary company information, valuable assets and cash, find great value in including the polygraph into the employment process
Using Polygraph to Prevent Losses in The Business
Retail, warehousing, logistics and mining industries, regardless of operation size, are always at risk of theft, stock shrinkages, fraud, syndication and sabotage. The process of routine polygraph screening tests acts as a proactive deterrent from partaking in these activities for employees in these industries. Routine polygraph testing allows for routing out syndicate involvement in environments where staff can become targets from outside influences to bleed companies dry. These routine polygraph tests can be successfully completed either by having staff be tested at set regular intervals, or with these tests being randomly scheduled.
Using Polygraphs as Part Of An Investigation
The implementation of polygraph tests is a robust tool for a business as an additional investigative step when the business has experienced loss, shrinkage or other cases of misconduct. This process allows the business to identify and determine the employee’s involvement in the theft or discrepancies that have occurred, further knowledge of the incident can be determined through the polygraph process.
Determining other breaches of contract for hearing purposes, such as substance use, or confidentiality breaches, can be incorporated into polygraph tests to validate claims and evidence already available in cases against employees.
When considering the use of polygraph testing for your business it is important to remember that the process for an incident that it should always be a part of a broader investigation. Polygraph testing should not be the sole deterrent in maintaining the trustworthiness of staff. Ensure that when using polygraph testing in your business that your employees agree to the process voluntarily and that the process is conducted ethically.
Any business can use polygraph testing at any time the business feels the need to add credibility to an investigation, to maintain work force honesty and to ensure employing the correct people into the business.
