The Bianca Butcher actress, who is taking a six-month break from the BBC soap, also revealed that she is looking forward to spending time with her four children.
Speaking on today's This Morning, she said of her future on the serial: "I'm really grateful that I've got such a good job, but at the same time I don't get paid for not going to work so in effect I'm losing out on six months worth of wages.
"You never know when they're going to do that on EastEnders. Obviously some amazing characters have been written out or died. They haven't written me out yet, but you never know."
Of her decision to have a hiatus, Palmer further explained: "Just when I went back after having the baby, I was signing a new contract and I just asked whether that would be possible.
"Because it's the school holidays between March and September, they're at different schools, the baby's only 16 months old.
"And it's quite hard to juggle it all. And I don't want to keep saying no to them all the time. If they've got something at school, I like to be involved in that."
Palmer makes her last EastEnders appearance before her Albert Square exit tonight (April 27) in a Bianca special, airing at 8pm on BBC One.
