What industry do you work in?
Alot of companies have sick time that is seperate from vacation time. Smaller companies may not have sick time but alot of companies have it. The type of industry you work in makes a big difference, agricultural, no way, construction, not very likely, medical, yes, finance, yes.
I don't know how many days you have missed because of injury but if its less than 10 days in the past year, I'd say it's not a big deal. Now if your gone for a month or two over the last year, then the others in the company may have been pulling your weight.
Good luck, ride safe.
