The Newport Crown Court jury heard Dr. Lucy Dawson, 45, took sick leave from the Royal Gwent hospital in Newport, Wales, by claiming to be "too stressed" to work, but secretly took on shifts at other hospitals to make extra money from the National Health Service, The Sun reported Tuesday.
Prosecutors said Dawson's bosses found out about the scheme from her Twitter account, where she posted about the "megabucks" she was making from moonlighting.
Dawson is charged with two counts of fraud by failing to disclose information. The trial is ongoing.
