These aren't the people being discussed though. In the OP it is an individual who won't hand over any work or accept help. Everyone is working with limited resources and is having to do more work in that period. In effect, I now have to also complete the work of 2.5 people in addition to my normal work based on 3 years ago.
However, if I've a quieter period or some slack in terms of the current priority project and a colleague is falling behind, I will offer to take work off them and vice versa. There are some, who for whatever reason refuse the assistance and would rather work 14 hour days (or say they do) even though there are ample opportunities to ease the workload.
My job isn't guaranteed, we're all under closer scrutiny, but I'll still refuse to take on work either internally or externally if I'm working on the day's priority. Some clients moan and even tell me to drop work I'm doing for other clients so their job can be done, I tell them that I will, but then only if they're prepared for me to drop their work when a different client asks me to do the same tomorrow.
And so on, blah blah blah. I've still got my job, I still get more done than most, it's all done in a manageable time and I even have the odd moment to post on here.
If employers still only judge employees by the amount of time they spend in the office rather than their actual output, then no wonder they're fighting to survive. It's like those statistics on some footballers who lack any real talent, contribute little, but because the stats show they ran around on the pitch for 90 mins non-stop and covered 15km, that some how that makes them a good player. Until it's actual productivity that's measured and not how long you're logged into the system, martyrs will exist and business will go bust.
