I lead several people who are matrixed into my product teams. I am not their line-manager, so I don't have the big boss sign above me that comes with the power to fire.
I am about ready to start one-on-ones with them and even have the e-mail ready to send.
Generally, my team members are agreeable to the tasks I assign them, but we negotiate when there are differences of opinion. I am concerned that they may push back about meeting weekly "just to talk". I can explain to them again (after the e-mail) the virtues of one-on-ones and that I think we should do them because they'll help us be more effective in our work. But, I can't order them to do one-on-ones since I'm not the boss.
Before sending the e-mail, should I try to get buy-in from their line-managers so I'll have support from the boss? Or, is that playing an end-around my team members that might erode trust between us? If their boss resists as well, do I just have to let it drop and not do one-on-ones?
I'd appreciate any advice on ensuring I can get the one-on-ones to happen even though I don't have the power to order them.
