We are a technology startup, the problem i am facing is that my colleague(same designation as mine) Manager A and a member of his team (Coder A) have become incompatible.. it started out with sarcastic jabs.. i mediated once around two months ago and made it clear to Coder A that he has to improve in his professional relationship management. Coder A has just 1 yr experience and really does not know what/when to say... A few days back the problem resurfaced and Coder A came back to me with complaint that Manager A is demotivating him by micromanaging him and telling very petty details while explaining tasks to do. I consoled him and told him to take things like these as Manager A is his big brother. We are a small team and we cant have issues like this plaguing our productivity. I discussed with Manager A and he is like i was joking which i find trustworthy as he really is the funny guy of the team. Manager A has given up on Coder A and has asked me to manage him.
This could work but i am a bit sceptical as the team is small and work load huge... we need everyone firing on cylinders... such problems unnecessarily damage the mood and productivity of people involved. One more problem is that Coder A's productivity is really low(from our expectation when hiring... he is from a top college).
The other angle which seems plausible is that Coder A knows that since there are two people at top he can be safe if he is in good books of one... so he just comes to me and patronizes me.... i do not have any proof so i am not taking any action...
How to deal with this so we have a good professional atmosphere between these two guys...Any ideas?
