Snas:
Taking BASSA's comments prior to the hearing, and Mr. Holley's commentary afterwards I'm going to go out on a limb and say I believe this was probably the result of a routine disciplinary hearing.
Mr. Holley is not giving any vigorous defense in his statements, certainly hasn't said that BA didn't have cause for the firing, and is only crying that it was "retalitory".
The interesting question is that given that Mr. Holley shows up for his Cabin Crew duties so rarely how did they notice he was gone
