Dynevor's alter ego Sally Webster offers Carla Connor (Alison King) to buy half the factory left by the evil Frank Foster (Andrew Lancel).
"Sally wants to focus on something other than a man for a change," she told Inside Soap.
"She's got the money from the settlement with Kevin and after working alongside Frank she feels she can do more than just be a machinist. Sally really wouldn't be at all happy if the deal fell through.
"She'd be a terrible boss - so bossy and self-righteous. I certainly wouldn't want to work for her!"
However, the 48-year-old - who has played the Webster matriarch since 1986 - revealed that she "desperately" hopes Sally finds success at some point.
Dynevor added: "Sometimes I desperately want Sally to be successful at something. But sometimes I don't want her to get what she wants because it makes it more interesting."
