My bonus paid out in April 2020 was cut by 0.3 months, I joined in 2019. I heard this was the same for grades 13-9. Senior management got 0.5 cut. My April 2021 bonus was lesser, even though they didn't have an official announcement it's a covid cut, but I think it should be because my rating was the same, doesn't make sense for the bonus to be lower than 2020 unless it's due to covid.
