Chas has been joint landlady at the village's pub for well over a year, but her future there is thrown into jeopardy in upcoming episodes.
Next week, Chas takes the blame for a failed robbery attempt at The Woolpack. She has arranged the raid with ex-lover Cameron Murray as Carl King is blackmailing them, but she protects Cameron by taking full responsibility when the truth looks likely to come out.
A furious Diane Sugden (Elizabeth Estensen) agrees not to report Chas to the police, but makes it clear that she wants her out as there is no way they can carry on working together after this.
Pargeter, discussing the storyline, commented: "I absolutely love Chas being at The Woolpack. There's definitely a few moments coming up where it looks like she might lose it, but I hope that doesn't happen as I love it there. I get to see everyone on a daily basis because I'm always filming there."
She added: "You hear all the gossip when you're working at The Woolpack, that's all I'm worried about!"
Viewers will see that Diane is devastated over Chas's betrayal, feeling that she has treated her like a daughter in recent times. However, whether she will give Chas another chance remains to be seen.
Emmerdale airs weeknights at 7pm on ITV1.
