unless you are working on an actual natural disaster and frankly sometimes even then,
don't take pride in doing quality work under terrible conditions. don't show off to your boss or your clients how you're such a spunky little scrapper that you can work with half-broken equipment, you can work all night to meet any deadline, you can maintain professionalism in the midst of chaos.
the lesson they will take away from this is that you never need functional equipment, sleep, or organizational support. (and that your coworkers/colleagues don't either. so if you can't summon up enough respect for yourself, do it for them.)
you have to let things fail sometimes. give me an impossible deadline, I'm missing it. schedule twice as many appointments as I can handle, I'm canceling half of them. put me in a work situation where the only way for me to win is to kick in my own time or money, then guess what, buddy, I'm losing and that means we're losing together.
understand, the flip side of this is that with adequate supplies and time I will put them to good use. this isn't spite, it isn't a threat to sabotage businesses. it's merely saying that if someone sabotages their own business, their employees are not obligated to save them from themself.
no more super worker. this is the decade of getting exactly as much worker as you paid for.
One of the most important things a mentor told me at my job is “Never give more than 90%. You need that last 10% to sustain yourself. You don’t have any more to give. If the library has to close because there’s not enough staff, then the library closes. That isn’t your fault.”
