Will my husband get paid a full check next week if he uses sick days this week?

My husband is using his sick days tomorrow and friday at work. We are planning on going on a vaction next weekend so my fear is that when he gets paid next week it wont be a full check. I called human resources and told her what days he is going to use and she said okay thats fine but his sick days wont go on his check until next week..........so i didnt understand that part..........can someone ease my mind in letting me know if his check will be the same next week as if he worked all week this week.........he gets paid weekly...........Iam a worry wort lol
