A tad extreme...
Perhaps BASSA should pause before issuing such overwrought statements.
To follow this logic, if this Captain is also a member of the Royal Horticultural Society then all lovers of roses and pentunias are strike breakers.
Unless this Captain makes a specific statement that he is taking such action AS AN OFFICIAL REPRESENTATIVE OF BALPA AND SANCTIONED BY BALPA then Balpa has no responsibility in this specific instance.
These postings by BASSA reps do not project either strength or professionalism on the part of their leadership.
