Sick leave , just make me sick.

With the swine flu, the new ward I am working has to close to deploy staffs to either medical/pediatrics/isolation wards. Today is the 2nd last day of my so-far surgical life, yet I was unluckily deployed to another surgical ward. The reason is because there's a shortage of staff in there, due to sick leave.
I am okay to go if people are really sick and cannot attend duty, but what I have been hearing today is that people may not be sick. I am indeed angry, but I can say nothing.

Is that what a nurse should be ?

A month of surgical life has already let me feel this department is just shit.
