Lawyers have warned bosses that employees are responsible for the majority of fraud cases.
Glovers Solicitors has said that fraud and personal data loss is a current concern with companies, which could mean bosses need to spend more time on the selection and recruitment of staff.
According to Tony Bourne, senior partner with Glovers, 90 per cent of fraudulent workers have been with their employer for more than a year.
Mr Bourne states that employers should think carefully about their contracts, adding in clauses that will deter such activity.
"You should also ensure that there is a contractual claw back provision which covers all monies owed including notice monies, holiday pay and bonuses and that you can contractually suspend the employee without pay, during any fraud investigation," he warned.
Employees should also undergo rigorous training and be aware of monitoring policies on emails and internet access.
Bosses were recently warned by the Chartered Institute of Personal Development that a different management style in the private and public sector was one of the reasons staff in the private sector are less likely to phone in sick.
