One of the newly appointed managers always keeping an eye and criticizing the habits of one of the employees. He always keeps getting frustrated for one or another reason because of him, As being close to the Employee (Team member of mine in the various project), I am sure that He is perceived wrong and being gaslighted.
A few days ago the manager in question
Walks into his desk just after lunch hours and asking him what he has completed till now since morning (even there were no clear guidelines of what needs to be finished).
As my colleague, was shocked to see his rude and inquiring tone, he took little time to express what he has done and what he was doing. (Its post-delivery bug fixing session)
After acting dissatisfied with his answer Openly said to him (my colleague) that from now onward he will not assign him a task and he(my colleague) can decide himself of whatever task he wants to do.
I find this behavior very shortsighted as well as confusing. Since that incident, the manager is giving my colleague a silent treatment.
It has become embarrassing for all to see my colleague asking for him list to the task to finish and he just saying him to do whatever he likes without taking an interest.
I am sure my colleague has never failed upon delivery timings in the past two years. What is the best thing he can do to solve this rift?
