Not that CGT would accept that removing the stairs while the door remained open was daft (not to mention against company policy), nor that the person who made the mistake should at least be suspended pending investigations:
PARIS (AFP) - Air France said it may have to cancel half its flights out of Paris' Orly West air terminal as a result of a strike by ground technical staff.
A spokesman said 60 or 70 flights out of a total of 120 might have to be cancelled.
The airline operates domestic and some European flights out of the terminal.
According to two of the unions involved in the strike, the stoppage could spread to passenger handling staff and to the main Paris Charles de Gaulle airport.
Hundreds of passengers were left stranded by the strike, which was called to protest the suspension of a gangway worker. (my emphasis)
The suspension followed the accidental death of a flight attendant who fell from the top of a mobile staircase as passengers were disembarking.
