Bosses are like women, both when hiring and when working. Neg those hoes. Play 'em...
With any job, they want you to work and they don't want to pay you for your work. Always show hi value, so that people value you. When they value you, they value what you do. Being NICE and doing everything does not get you higher in the ranks. If you have to step outside your job description, make sure they know it and appericate what you do, and that you get rewarded.
In other words, if you doing something out of norm, make sure they are not setting a new frame with you. Remember, they are using your time to get work done, either they respect it, or else you don't do the job.
NICE guy bull sh1t don't get you anywhere. In my AFC days I staid over time on christmas eve to get the bosses van fixed... Then in February I got fired on my birthday for dropping a printer. Never be nice - in fact, once you a playah, that NICE idea isn't really nice anymore, if you know what I mean.
