Final answer:
The questions' terminology about 'multi employer RA IC' and 'pseudo RAICS' for Toronto airport employers is not standard; the response focuses on the importance of equity and fair hiring practices as supported by academic research.
Step-by-step explanation:
The question appears to be regarding the amount of risk assessment and internal controls an employer at Toronto airport should have if they have multiple job openings. However, the acronyms 'multi employer RA IC' and 'pseudo RAICS' do not correspond to standard terms used within human resources, risk management, or employment law. Instead, the area of focus should be on equity, fairness, and anti-discrimination practices within the hiring process, which is where the provided references are relevant. Large employers, like those potentially at a hub such as Toronto airport, must comply with fair hiring practices which includes mitigating any implicit bias against racial minorities or any other form of discrimination.
Studies such as those conducted by Banerjee et al. (2017) and Behaghel et al. (2015) examine the fairness of large employers in hiring practices. Moreover, Gary S. Becker's economic analysis offers insights into the costs of discrimination for employers. When considering how much 'multi employer RA IC' and 'pseudo RAICS' would be necessary, it is vital to align hiring practices with the principles of equity and fair treatment outlined in these studies rather than to seek specific quotas or numerical indicators.
