So, near graduation interns got axed for a dress code petition. I guess I'm an old Baby Boomer too; because if I was managing a bunch of near 20 year old interns at a company and they hit me with something like this; I'd have shown them the door too.
As an intern you're there to LEARN and GET real-world experience. If a few of them had come and ASKED about why something is the way it is - I'd have told them, and taken any input they had, evaluated it, and answered further; and sent them back to their duties. But yeah if out of the blue they hit me with a signed petition and arguments about something as trivial as the company dress code; not really asking anything beforehand...buh-bye.
