Margaret Burnett, 69, stole the money from five residents at a Leonard Cheshire home in Edinburgh between January 2014 and August 2016.
Burnett, a team leader at the supported accommodation facility, was sentenced at Edinburgh Sheriff Court after pleading guilty to a charge of embezzlement.
She illegally used bank cards belonging to five residents to make numerous withdrawals from their accounts totalling £29,900.
Burnett was placed on a 12-month supervision order and made subject of a restriction of liberty order.
She was also ordered to pay those victims of her offending who are still alive £3000 each in compensation within 28 days.
Neil Almond, interim Procurator Fiscal for Lothian and Borders, said: “Margaret Burnett committed an egregious betrayal of trust.
“These residents depended on her to play a part in their financial arrangements. But she flagrantly abused her position to use their money for her own benefit.
“Let the public be assured that we take such financial criminality extremely seriously.
“Those who commit this type of offending will be dealt with robustly by the Crown Office and Procurator Fiscal Service.”
Prosecutors said Burnett had been employed at the charity for 13 years and had worked her way up to the post of team leader.
This gave her access to the home’s safe and a locked cabinet containing residents’ banking cards.
Their finances were controlled by staff and all transactions involving their accounts were officially logged in a cash book.
In September 2016, the charity was contacted by the Royal Bank of Scotland who had identified ATM withdrawals totalling several hundred pounds from one resident’s account.
Officials from the charity then discovered several withdrawals of between £100 and £300 which had not been recorded in logbooks or the residents’ diaries.
Police were alerted to the situation by the home’s management and a subsequent investigation found the bank accounts of five vulnerable service users had been accessed by Burnett.
The court heard Burnett used the bank card of one victim while he was in hospital and “physically unable to withdraw the cash”.
One victim, who has since died, had cerebral palsy while another suffered from multiple sclerosis.
Burnett was suspended and then dismissed from her job before being arrested in November 2019.
Following the police investigation, it was estimated that Burnett had embezzled £29,900 from the five residents.
