A close relation works for a small Irish company.
The company has 2 sections, one being seen as 'bigger/better' other one within the company.
The relation involved is head of the smaller division. They were sent by the company for further education with a view that they would be put in place as head of the 'bigger' division upon completion.
However, since the relation returned to education, a temporary worker, who is british, was put in place as vice head of the bigger division. This worker has since been made permanent.
In order for the relation to progress to head of the bigger division, they have to spend time training in the position of vice head of the bigger division.
The relation has returned to head of the smaller division because the company have told them that, due to personal tax implications for the british worker if they moved to the smaller division in order to let the relation train in the bigger division, they cannot do it at this time.
(it must be said that the nature of the work and rotas means that the british worker is still UK resident for tax but claims back irish tax paid through PAYE. He would end up paying more tax overall if working in the lower division as the rotas are slightly different)
The relation has been informed that this is the sole reason for the halt in his progression.
My question is, could this be seen as discrimination because the Irish worker cannot progress due to the fact that a UK national will end up paying more personal tax? Effectively the relation cannot progress further because of being Irish?
If the said UK worker was Irish, then there is no issue.
