I don't think this thread is 'negative'.
Instead people are making very realistic comments about what it can be like to be an older worker.
As a part-time worker with a long term health condition classified as a disability, I have been treated very poorly by several employers (lack of progression or pay rise, discrimination, being taken from granted), patronised by younger colleagues and I have found it trickier to try to secure new employment. Those are facts.
I am not going to 'go the extra mile' or whatever nonsense my employer comes with if they treat me like an easily replaceable commodity.
Of course it is different if you have a decent, flexible job and your work is valued and rewarded.
I am looking at doing things like retraining, going freelance and so on as I have to keep working but I am quietly quitting my current job because they are only too happy to exploit me without giving much in return and I am done putting up with office and corporate bullshit.
Also having had some serious health issues I came to realise that work is not what matters the most in life.
I just need to make enough to live on but I am not dedicating my life to working for an employer who does not give a damn about me.
