I am not sure there is another jurisdiction that has it specifically in its labour code that an employee can ask for flexible work arrangements, probably because it's not that meaningful. Employees do ask for flexible work arrangements all the time.
The bigger problem is that employees are being made flexible when they don't want to be flexible—workers who are casual, temporary, on call, or on contract. The labour code really needs to be updated to deal with that situation, especially when people are being kept as temporary employees in permanent positions, so that they never get to be permanent even though they are really doing a permanent job.
