The employment laws are different and they favor Irish employees. There can be other factors, for example, some companies handle layoff in the US using part of organization that is abroad. In addition to different employment laws, suing the Irish organization by a US ex-employee is practically almost impossible. Expenses and time required are prohibitive to an average employee.
Consider this for a next position in international organization.
