As an Airtasker Worker and a committed member of the Airtasker community, it's important to remember that when your offer is accepted on a task, it's expected that you complete it.
Although you may need to cancel a task, it could result in a temporary 24 hour restriction if you're the reason for the cancellation. This is regardless of who starts the cancellation process.
The temporary restriction will be waived for first time offences. Thereafter, the restriction applies to making offers, commenting on tasks and posting tasks; however, it will not restrict you from completing tasks that are already in progress.
We're sure that you would like to see more tasks being posted, giving you an opportunity to earn more. So it's important to understand that a positive experience is necessary and that task cancellations can have the opposite effect.
