Afterburn,
I won't sit here and presume to know about your financial situation, but please, think about the long term. This is a slippery slope if I've ever seen one. Pilots may not be as high and mighty as those of yesterday, but we are not that low either. Management does everything to put pilots down, and we don't help by arguing amongst ourselves. Why should we help them push us further down? What if management says they'll pay less now that this tip system is in place?
As a pilot, you are a highly skilled professional. You do not get tips.
