Bonus affected by start date?

First year analyst at a BB. We get paid bonuses end of June, so still far away. Under normal circumstances, I think training starts about a month sooner than it did for us this year because of Covid. Might be negligible but wondering if you guys think banks might use later start dates as a justification to pay slightly lower bonuses (e.g. if you expected a 50k bonus, turns into 45k or something)?

Obviously just speculation at this point but want to hear people's thoughts.
