Does it bother you when a co-worker keeps talking on phone all day long and it's not work related? It bothers me.

Most of the time I'm busy with my own stuff to notice all these things around

Despite the fact that like @aitkotw I'm normally too busy to notice that, I have the "curse" of being the "senior/boss/supervisor" of a coworker that do that too often... So I notice that more than I like, but the right amount to scold him harshly

@0x412E2047696C I wish I have the authority to scold. But I'm not for his productivity. If he's on phone I'd like him to go somewhere else and finish it instead.

this is why i bought some noise canceling headphone

Back in the day, we had a similar problem with a designer, she’d spend hours on private calls. We got a big cardboard box, cut some windows and stuck some clear plastic sheets on the inside and painted it red (to resemble the old british red phonebox). Then we put it over her head. we all laughed as she got progressively more angry. Comefy is my cure.
