I’ve worked for a couple of non-Asian companies and the one thing that gets me insanely irritated is having to adapt to the timezone of wherever their headquarters is located. If in Europe, that’s not too bad – Asia still has some overlapping work hours. If in the US, good luck – early morning conference calls at 6am or late night calls at 9pm are the norm. Although annoying, I do accept that these situations are sometimes inevitable for work productivity.
What I can’t accept is when companies take employees having to work in a different timezone for granted, especially in cases when the employees aren’t paid an early morning or night shift allowance, or allowed flexibility to come in later or leave the office earlier (i.e. “deducting” the hours from their normal working day).
