Last week, the C shift maintenance crew visited Mandurah Primary School to put up a garden shed.
Crewmember Grant Orr’s wife works at the school, so this gave him the opportunity to help.
Mr Orr said once a week 50 to 60 men from the plant left work to voluntary jobs in different locations.
Gardener Shelly Podmore said without their help she would be relying on volunteers from in the school, which can be hard to come by.
The shed would make her job easier by giving her a place to store her equipment.
