Explanation
Evidence to support the argument that racial discrimination is a serious problem in Company G is as follows:

The figures in the report of 2014 showed that the workforce mainly consisted of white and Asian workers. Even the follow-up report revealed that black constituted the overall percentage with single digits.
There is no performance-based reward structure and system for employees with diversity and inclusion at the workplace.
Evidence to support the argument that reverse discrimination is a serious problem in Company G is as follows:

Company G was sued for gender and race discrimination against white males. As a result, the discrimination that happened against the dominated group in respect of a minority group became a serious issue of reserved discrimination.
There was an effort from recruiters to increase the number of unrepresented groups, which somehow overlooked the white men who were present in the process.
