Low bonus - discriminated because of my immigration status ?
I received a 50% bonus cut and I’m down 5% total comp. performance was very strong according to the review. My manager said he is not responsabile for it and that my hiring manager is. He mentioned that it might be because my work authorisation expires in 10 months and HR did not identify a way to keep me working here, and so they might not have been incentivised to reward me as I should have had. Another colleague with visa issue had also a similar experience.
Is this legal or is it discriminatory ?
