The daily work has to matter
With a Scorpio Sun in the 6th house, an ordinary job is not survivable for long. You need the work to have consequence in it: something at stake, something that would go badly wrong without you, something real. Otherwise the days become genuinely intolerable rather than merely dull.
This is why people with this placement often end up in demanding fields that others avoid, and stay in them far longer than seems reasonable. The intensity of the work is not the cost; it is the reason it is bearable.
You can hold pressure for a very long time
Sustained difficulty does not break you the way it breaks other people, and you will keep functioning through stretches colleagues could not manage. That capability is real and it is dangerous, because the absence of an obvious limit means you find it by passing it. Set the boundary by clock and calendar rather than by how you feel.
Colleagues cannot quite read you
At work you are competent, contained and difficult to interpret, which earns respect and slows trust. Some people assume you are judging them. Give away a small amount deliberately: one ordinary fact about your weekend, one admission of a mistake. It costs nothing and it changes how the whole team experiences working beside you.
The trouble you can see coming
You detect the failing project, the colleague who is not telling the truth and the process about to break, well before there is evidence. Raising it makes you look suspicious rather than perceptive. Say it in terms of the risk rather than the person, and put it in writing, so that when it happens the record shows you named it.
Knowing when to stop
The recovery here is as intense as the effort and it has to be scheduled, because your instinct will always be to continue. Book the break before the demanding period rather than after it. A person who only rests when incapable of continuing eventually finds out where that limit actually is, and it is an expensive way to learn.
Send you where it has gone wrong
Investigations, turnarounds, crisis work, anything requiring somebody to look at the real situation without flinching: this is where your value is highest. Routine administration is not, and it leaves you looking like a worse employee than you are. Position yourself as the person who handles the difficult account, and negotiate the terms before you accept it rather than afterwards.
You find the limit by passing it
Because you tolerate strain rather than registering it, the warning signs arrive late and all at once. Use external measures instead of internal ones: hours worked, nights of poor sleep, weeks without a full day off. Numbers you agreed in advance, while calm, are the only warning system that works here, because the internal one reports nothing until it reports everything.
Two colleagues, both of them real
You will not have a wide circle at work and the one or two you trust know things nobody else does. That is a good arrangement and a fragile one when somebody leaves. Keep one professional friendship alive outside your current employer, deliberately, because rebuilding this from scratch takes you years rather than months.
Priced for the thing nobody else will do
The work you take on is the work others decline, and that scarcity is your pricing power if you are willing to use it. Name the number before you agree to the difficult assignment. Afterwards there is no leverage at all, because the crisis is over and you have already handled it.
Rebuilding after the thing you fixed
A working life spent in demanding conditions leaves marks that show up years later, and nobody is keeping account of them but you. Take stock at the end of each difficult period rather than moving straight to the next one. A fortnight of deliberate nothing after a hard year is the maintenance schedule for this configuration.
