Be kind to new staff. That is needed for everyone. Enshrine the rule so that looking after newbies is important. See newbies as people that need to be challenged, yes. Where does the challenge stop though? What is it to make someone prove themselves and what is it to try to break them? And by break, I mean to make them flee the school.
This school is capricious and cruel, or at least those immediately above me are. They view themselves as being solid amongst themselves.
I am seen as someone who tries to make the management of things difficult. That I overcomplicate things. That things that should be easy to manage become difficult.
I need to dedicate my mind to things worth dedication.
