MON have been taking several ex TCX F/Os on career breaks. The poor chaps had seen their careers grind to a halt and needed to get out to an operator that appears to offer a future not involving the constant erosion of T&Cs. Grass greener? They'll no doubt let us know in due course.
For those casting around for a summer job I'd certainly put Monarch above TCX on your list. Most other airlines too. Except Ryanair. Obviously.
