If the organisation was aligned with the workers already, then I see no reason for it to be unaligned with a union.
Though the question is; if the workers and organisation were so well aligned before, why did they unionise?
Possibly the organisation isn't well aligned and the conflict will come from unrecognised differences. Progress will be made by not demonising the union but working with the counter weight as a legitimate part of the process.

All possibly true, although sometime disaffection comes from a privileged group acting from an unfounded sense of grievance… in my experience par for the course when dealing with ‘leaders’ in conservative christian circles (which describes this institution well)
