This is why I don't like Air Canada non-management ground staff. The overall quality is just shoddy.
I remember how pleasant it was to check in when the unionized employees went on strike and management handled the check in. This was several years ago when everyone said the sky was going to fall. Check in was such a pleasure when the unionized employees went on strike.
They should also realize that the SEs probably have more experience than they do in terms of deliverables.
