Methinks many would benefit by investing in a mirror.
Who is responsible for your safety ? Your health ? Your well being ? Who cares about these things ?
Pull out the mirror.
Who are you screwing if you work when you don't want to or shouldn't ? Pull out the mirror.
If you wanna work or think you should work over xmas / New Years or whenever work. If not figure a way not to. Why is anyone worried about the mission at this point ? How valuable--really--are all those gold stars in the grand scheme of life. You're not screwing others and they can buy a mirror too. Why would you solve scheduling problems for others when they've demonstrated this is not a two way street ? Things are NOT going to change in the near future. There might be an epithany at some time, but that some time lies down the road and won't happen until management figures this stuff out for itself. Sometimes, despite your input and warning, you have to let the kid put his hand on the stove to figure out its hot and it hurts.
IF you put this job ahead of your family, health, self, or friends I'd submit you are making a serious error you will probably regret in your later years. IF you really enjoy what you're doing and where you're going by all means have at it. But look at the big picture of things. At this point, who cares more about you and your well being--your family or the folks running the place ?
And look in the mirror. Because the person staring back at you is the only one who is gonna fix things for you.
Life's about the journey. Not the toys or money you wind up having when they close the lid.
