Maybe it's a cultural thing. Unfortunately if left unabated, it could get us into trouble as we grow up. More so as we mature and turn into professionals.
As a work at home professional, I work US hours. Actually it's a compromised US hour. I start my day at 3pm Manila time and finish my shift at 12midnight. Translated to Eastern Standard Time (EST), I work from 3am to 12noon. However, some of my colleagues would set up meetings way past this hour, or afternoon their time. This leaves me feeling very conflicted. Since I am already at that stage where I don't receive overtime pay, there really isn't any benefit for me should I decide to extend my working hours. In which case I always have a couple of standing questions I ask to help me decide whether to accept a meeting invite or decline;
The first question is:
Are we racing against a very tight deadline? If yes, I then ask myself, do I play a part in meeting that deadline? If again I get a yes, then there's no escaping it, I have to attend that meeting.
