Note - if a medical professional is saying someone is unfit to go to work and needs some recovery time, that's different. I'm talking about self-proscribed mental health days.
It's one of several things people are very confident are good for mental health, but I've not seen it actually pushed by any mental health professional (at least, not in the way that it's often used).
I'm not totally against the idea of "chucking a sickie" (a time honored Australian tradition) to get some personal admin done, or just take a break. But I've seen no evidence that it's a good coping strategy if you're got actual problems.
If there's a problem at work, you're better off actually dealing with it either fixing the problem (which might be you or it might be external, or a bit of both) or looking for a new job.
Many mental health problems are cycles of short-term rewards for long-term pain, a lot like addictions. I think this is basically the "B" in CBT - maladaptive behavioural responses to stressors (which need to be replaced with more useful responses) - https://en.wikipedia.org/wiki/Coping#Negative_techniques_(ma...
> Whereas adaptive coping strategies improve functioning, a maladaptive coping technique (also termed non-coping) will just reduce symptoms while maintaining or strengthening the stressor. Maladaptive techniques are only effective as a short-term rather than long-term coping process.
> Examples of maladaptive behavior strategies include dissociation, sensitization, safety behaviors, anxious avoidance, rationalisation and escape (including self-medication).
> These coping strategies interfere with the person's ability to unlearn, or break apart, the paired association between the situation and the associated anxiety symptoms. These are maladaptive strategies as they serve to maintain the disorder.
Note, I'm not an expert on this. But I suspect neither are a lot of people disagreeing with me.
More generally, a lot of what seems like "good advice" on mental health could be just reinforcing maladaptive coping techniques, because the seem like common sense (they are how many people cope with problems, even though they're not helpful in the long run).
And I'm guessing that the people who would be most harmed by bad advice (or advice that might be good in some situations, but bad in others) will be the people probably should be taking very different advice (e.g. "deal with those underlying problems" instead of "take a day off if it's getting too much").
