If all Nichol Kessinger did wrong was have an affair, why was she fired?

According to the Times-Call:

During this interview, Kessinger gave Koback her phone and signed a waiver allowing him to look at phone calls and texts between her and Watts. While Kessinger questioned why investigators needed everything from her phone, she consented to let them search it. Much would have to be recovered, though, as she had deleted everything involving Watts after she discovered he was lying to her.

“Initially, you drew concern from me when you told me that you deleted everything from Chris,” Koback said, but it appears that concern dissipated. Toward the end of the interview, he told Kessinger to take her mind off the case for a while, suggesting she go out with a friend and relax.

But Kessinger was concerned about the long-term effects of her connection to the case. When Koback said she looked tired again, she said it wasn’t just because of the shock of what Watts did.

“I lost my job yesterday, so that’s where that comes from,” she said. Kessinger had worked for Tasman Geosciences, which contracted with Anadarko Petroleum Co. She told the company her situation a few days after Watts’ arrest, she told Koback, and at first they said it was fine. Aug. 22, a day later, they said they were letting her go because her contract was up.

“I have a feeling that trying to get by for the next five to 10 years is gonna be really hard,” she said.
