"Hate" is a big word for what is usually a specific, nameable absence — and the reason it feels like hate is that the absence has been going on for a while and has stopped being visible as a single thing. So the first task is not to decide whether to leave. It is to find the noun.
What is usually going on
The work is not your kind of work. You are organising when you want to be making, or persuading when you want to be understanding. The day is full of the wrong verb. This produces a dull, constant drag that gets called hate because it never lifts, and it does not respond to a better manager or a raise.
A value is being starved. The job is fine in every way except the one that matters to you. No growth in a place that has stopped growing. No autonomy under someone who needs to see the method. No way to name who the work helps. You may not be able to name the value yourself — people rarely can — but you can feel its absence as a kind of pointlessness.
One person. A manager, a colleague, a client. Everything else is fine, and one relationship poisons the day. This is the case most likely to be mistaken for hating the job, and the one most likely to end on its own — people move — or to be worth escalating rather than leaving over.
Burnout. If it is not only the job — if the weekend is grey, if the things you used to like are flat, if you are tired in a way sleep does not touch — then the job is not the problem, or not the whole one. Quitting from empty does not refill the tank. Rest first, then look again.
What to do tonight
- Find the noun. Finish the sentence "what I actually cannot stand is…" with one thing. If it takes a paragraph, you have not found it yet.
- Check the weekend. If it is grey too, this is burnout, and the decision waits until you have rested.
- If it is one person, write down what specifically they do. A pattern is something you can raise; a feeling is not. Raise the pattern once, clearly, to someone who can act, before deciding to leave over it.
What it depends on
Which of the four it is decides everything: the wrong kind of work means a different job; a starved value means a different kind of employer; one person means a conversation or patience; burnout means rest. The values test tells you the second with some precision — it names the thing you are working for, and lets you see whether the job could ever provide it.
