isn't it natural that the deputy manager should seek advice and direction from the manager, esp if feeling overwhelmed.
what is the alternative, to simply fail to deal with situations and not involve the manager.
we often hear of scandals in social work where there has not been proper supervision, and overwhelmed workers have failed in their duties, with managers being unaware, uninvolved.
your situation may be different.
but it depends how you raised the issues.
i suggest put everything in writing, in a calm official manner, with your observations and suggestions, and asking for feedback.
