I'm going to get 2 women at my office fired
Oh no, why would you do that? What did they do?
Neither of them work very hard so I want them fired.
Getting someone fired at work on purpose seems a little harsh. Understand how difficult this may make things on their families.
I'm paying for their salary and deserve better.
It is completely fine to let them go since you do need to have solid employees working for you. Just try to give them notice and understand that they have families that they support.
