Some teams say they need more people to get everything done that they need to do on time. My team works really hard, and yes, sometimes we put in extra long hours to get something out the door, but it's worth it. Most of the time the hours are pretty normal.
I haven't worked at any tech company where the teams don't want more people, so maybe my perspective is different. People seem to have great work-life balance, and we are accomplishing a lot this year, so maybe it's not as bad as some people think.
