Is my employer in the wrong?

A couple of months my job was on the verge of closing down due to not being able to keep employees. But they end up fixing the problem. My employer told all of the employees they were going to everyone a $1000 dollar bonus if they stayed. Well they ended up adding the $1000 dollars to our pay check which of course tax’s were took out. Now all of the employees are upset, because they were expecting the full $1000 dollars. We brought it up to our employer. And they didn’t care they told us we should be grateful we still have a job. Is my employer in the wrong?
