You do not do a job, you take it apart
You do not perform a task, you go into it. Mars in Scorpio in the 6th house sends complete engagement into daily work, so the routine job gets a level of attention it did not require and produces a result nobody else could have reached.
The sign is why the involvement is total and the house is why the material is ordinary. That combination makes you formidable at anything requiring persistence into unpleasant detail, and it makes an uninteresting job genuinely unbearable rather than merely dull.
The problem you will not leave alone
Given something broken that nobody has been able to fix, you stay with it past the point where everybody else has moved on, and you generally find the cause. That capacity is rare and it has no off switch. Decide in advance what the thing is worth in hours, because your instinct will spend considerably more than that.
Colleagues find your intensity slightly alarming
The concentration, the unwillingness to leave something half-done, the fact that you are still on it at eight: people notice and some of them find it uncomfortable. It is not a fault and it does affect how a team works around you. Say plainly that the pace is yours rather than a standard, or it becomes one by implication.
Half measures are what actually annoy you
Not volume, not difficulty: the thing that produces genuine anger is somebody doing a job to a standard they know is inadequate and being fine with it. That reaction is accurate and it comes out as contempt rather than as feedback. Say what specifically was wrong, once. The contempt is legible and the correction is not.
Running the body at campaign intensity
You push through things that stop other people, and your threshold is high enough that a signal has to become loud before it registers as anything worth attending to. Nothing dramatic is coming to make the decision on your behalf, and the tolerance itself is what makes the arrangement risky. Put the checks on a fixed date rather than waiting to be convinced, and treat rest as part of the operation rather than as an interruption to it.
Somebody else has to call it
Your tolerance means the moment other people would stop passes you without registering as anything, so the judgement cannot be internal. Give one person you trust the standing authority to tell you that you have had enough, and agree in advance, while nothing is happening, that you will treat what they say as a fact rather than as an opinion to be argued with.
The mess with two failed attempts behind it
Given something that has already defeated other people you become genuinely engaged, and the harder the history the better you work, which is a preference almost nobody else in the building shares. Ask for those by name rather than waiting to be assigned one. Say plainly at the interview that difficult and unpopular is what you want, since nobody will guess it and everybody has a list of exactly those.
The colleague who saw you at your worst
Your closest working relationships were forged in something genuinely difficult, and once somebody has been through that with you they are in permanently. Everybody else remains an acquaintance regardless of years served. That is a clean arrangement and it means a quiet job produces no friendships at all, which is worth planning around.
The unpopular job is the one with pricing power
The tasks you gravitate towards have bad reputations and high actual value, and they are almost never paid accordingly because the organisation feels relieved rather than indebted. Difficulty is the one thing nobody argues about when a price is attached to it. Name the figure before starting rather than after, since the moment the problem stops being frightening your position weakens completely.
Devotion delivered as maintenance
You express commitment through the unglamorous daily upkeep of somebody's life, done thoroughly and to a standard nobody requested, and almost none of it is ever mentioned by either of you. From their side it can read as habit rather than as choice, since the two look identical from outside and only one of them is exhausting. Say once what you are actually doing and why. It is not a claim on anything, it is information they do not currently have.
