To begin with, if you have to ask what "work to rule" is, you're not a pilot.
But - to answer your question.
"Work to rule" is NOT an illegal job action. All it means is that in these trying times, pilots may find themselves distracted by all of these outside influences. In order to remain SAFE, the ASA pilots should redouble their efforts to be SAFE and fly EXACTLY by the book. Review the POH and the FOM and fly in accordance with them.
