Wife jealous of my work benefits. Is this normal?

Hello, is it normal for one s spouse to be jealous of work benefits. I have a full-time job and she has a part-time job. She has never been interested in working full-time. However every time I use sick leave she gets really mad at me. Most of the time I just work half a day when I m sick that way I get home after she has left for work. Also , when upper management takes me and my fellow supervisors out for lunch she gets insanely upset with me. She doesn t like the fact that I have wellness time either. Is this normal? I d like to think that if she got benefits like this I would be happy for her. However it when I use my benefits(except for my tuition reimbursement benefits) it always leads to her resenting me.
