Trusting management, really?

Today I read an article about a school district that was allowing Principals to have the latest technology, (read it here) iPads, in order to give immediate feedback to staff that they observe and then move on. The comment on the piece from a parent was bemoaning the waste of money when schools needed more funding in classrooms.

I will not argue about that sut, seriously, do we not want our leaders to have the best tools to do their job. If it is all about saving money why not have the Principal teach? It would save one teaching post and we could buy more 'stuff' for kids. The reason we do not is because we need our Principals doing their jobs to the best of their ability and with the best tools. I believe they do not invest in their own equipment enough because they fear what staff will say.

We constantly see calls for management to trust staff, is it not time to trust management?
