From a former recruiter:
1. Are the crew in the same place as the call centres?
2. Do they want to do the job?
3. Are the skill sets the same? (no!)
4. Are the employment terms the same?
5. What ramifications are there for employment models elsewhere in the group?
6. Does temporary redeployment add to costs (in things like increased redundancy cost liability)?
7. To what extent are the call centres counter-seasonal to the airline?
