Most companies have a clause in their employment contracts that forbid employees to talk to the press without prior company approval, (usually refused,
PR matters dealt with by management).
The incident, by various channels, Ops. Engineering, Crewing, Traffic etc. will quickly become known to the duty manager of the day/night and the rest of management fairly quickly after that.
The captain will probably be required to submit an Occurrence Report, depending on the seriousness of the incident, airline management may stand the crew down immediately and instigate an enquiry.
What happens to the crew will depend on the results of the enquiry and once stood down, if members of a union, then they will be wise to contact the union and it is possible the company union rep. will contact the pilots even before they contact him.
That is just a start, there will be plenty more to come I expect.!
