I'm going to have to leave my job

I work for the federal government. Tomorrow I will be putting in for the deferred resignation. I'm not relying on getting paid during the time period (until 9/30). My job marks me absent without leave since I cannot keep sick time or annual leave banked up to cover sickness of the 3 kiddos I got. Tomorrow I am putting in my resignation so I don't get fired. I'll be pulling my kids from the daycare they thrive at so I don't get fired. Fuck the system

Edit to say: my position is one from being exempt. I cannot even if I wanted. Next is i completely support the administration and agree with what is going on. I'm not sure why there's so much hate going on.
