We should not assume this is down to a lack of management skills.

An employee who is the subject of gaslighting will likely, certainly initially, struggle to understand what is occurring – similar to Bergman’s character in the film. Psychologists describe Gaslighting as a subtle but unhealthy manipulative behaviour. Her husband convinces her that she is imaging things, when in fact he is scheming with criminal intent. Bergman’s character marries and mysterious things start to happen to her in her marriage. The term Gaslighting is based on a 1944 film ‘Gaslight’ starring Ingrid Bergman. Historically, we have described these practices as ‘subtle workplace bullying’. Sadly, these unacceptable practices are commonplace. The results are presented in the results section of this article.The term Gaslighting is a ‘label’ which embraces a cocktail of inappropriate and often manipulative workplace practices. Then this optimized model is compared with real state before optimization. On the basis of input data, it is created the model of indoor illumination of real working environment which is subsequently optimized in accordance with standard: STN EN 12464 – 1: Light and lighting Lighting of workplaces. Presented article is focused on illumination simulation of working environment during testing of cutting materials durability by simulation software Dialux. The suitable illumination is possible to ensure by modelling in various simulation tools.

It is necessary to create the suitable illumination of environment for the sake of interpretation of needed working performances and provision of efficiency. Illumination in the workplace is one of factors, which substantially acts on worker, his performance, error rate and last but not least his health.
