I have a deputy manager who is quite new in post. He's doing okay but is very ambitious (great) but sometimes a bit cavalier about some of the steps he will need to take on the way up.
I've let him know this but also given positive feedback where warranted and arranged for him to assist in a project he was particularly interested in that wouldn't otherwise have come his way.
On Friday he sent an email to our department strongly urging staff to get involved in a project another manager from another department is trying to get off the ground. he said he'd done xxx and other manager would appreciate volunteers. He CC'd in the other manager like he's our line manager FFS. He's not, he's the same level as me. Deputy had not discussed it with me at all and I feel it's massively over stepping the mark. Staff will see it as an order, or be confused and I don't particularly want them involved in this project as we have our own stuff to be doing. Other manager is favoured by upper management, but that's not the point and I feel deputy should remember who his boss actually is.
I want to have words to that effect tomorrow, but is it just me who would feel this way?
