To begin with, gender pay gap is the difference between the median annual pay of women and median annual pay of men.

As it has been revealed that working women are paid significantly less than what working men are, this tells us of the existing pay discrimination in workplaces. 

In 2018, groundbreaking legislation compelled many companies to reveal their gender pay gaps. According to the report send by companies to the UK government, most companies, especially those from the construction industry, were found to have the highest gender pay gap. They paid 25% more to male workers when compared to the pay of female workers.

Through research, it has also been found that men are mostly the ones that are at higher levels of the corporate ladder while most women are at lower level positions. This means that men make most of the money, leaving women with lower wages or salaries. One of the main reasons why women have reduced wages is due to the interruptions they have like child-rearing, which makes them break away from work for a time period. Companies want a continuity in work so this somewhat gives them a lower confidence in hiring women in big positions even if they have the necessary skill set. 

Within-job segregation is another thing that occurs in some workplaces whereby men are paid more than women despite both holding the same job position or comparable work experience. For example, let's look at the American multinational Google. In the past, it had segregated women workers by paying them less even if they were doing similar roles to that of male workers at the company. This behavior showed Google's pay discrimination towards women. A lawsuit was also filed against the company as an outburst by women workers of the company itself.  

Hence, an effective way to move forward would be to add undaunted legislative pushes along with relevant support structures, to shape companies' behaviors' in terms of pay into one that does not bring gender into hiring new candidates or in the promotion of existing employees whether male or female. If this is carried out successfully then there will soon be a time when gender pay gap will be zero, implying that our corporate world would be a better place.
