Whether it's company-organised volunteering, or someone simply passing a collection bucket around on a Friday afternoon, more Australian companies are finding a boost to morale and engagement when employees are encouraged to give.

According to a new study to be released on Wednesday by the Australian Charities Fund and the Centre for Social Impact, people who are involved in workplace giving programs are likely to stay more focused and motivated towards their employers.

More than 4100 employees throughout Australia were part of the study and more than 40 interviews were conducted with the top executives from large organisations in government and private sectors.

Australian Charities Fund chief executive Edward Kerr said more than 3000 Australian employers enabled workplace giving, reaching about 3 million employees.

Workplace giving is the contribution of money, time, skills and in-kind support by employers and their employees.

Gavin Cornish, the contact centre senior customer service representative for iiNet Canberra, said he was extremely proud of the workplace giving programs.

"We have many charity organisations to which we donate every month, like Leukaemia Foundation, Cancer Council Australia, UNICEF China, Lifeline Australia and a lot more,'' he said.

"At the end of the year, all the staff members vote and choose charity organisations.''

Chris Wheeler, a Canberra-based partner at King & Wood Mallesons lawyers, said the company ran mature giving programs that were first organised 11 years ago.

The Australian Charities Fund is keen to invite organisations across the ACT to get involved in workplace giving - retaining the employee and employer relationship.
