A dozen Perth truck drivers were ripped off a total of $93,000 as a result of their employer paying them the wrong cents-per-kilometre rate.

Twelve drivers from a local transport business have been back paid following recent intervention by the Fair Work Ombudsman.

The workers were paid below their entitled rate for long-distance trips across a 12-month period in 2011-2012.

Fair Work Ombudsman Natalie James said the case highlighted the importance of employers being fully aware of minimum wages and entitlements that apply to their employees.

"If left unchecked over time, a small underpayment can result in a hefty bill when discovered – a bill that most small business have not budgeted for," she said.

Ms James says that in each, employees were back-paid all money owed without the need for further action after Fair Work inspectors contacted the employers and explained their obligations.

"We're satisfied the underpayments were inadvertent," she said.

"Our inspectors assisted the employers to voluntarily rectify the underpayments and helped them put processes in place to ensure they comply with workplace laws in the future."

The Fair Work Ombudsman's website contains a range of tools and resources, including PayCheck Plus and an Award Finder, to assist employers calculate the correct wages and entitlements for employees.
