Gentlemen (and ladies), your only decision is which Monday morning none of you report for duty.
Until such time as that happens, you will achieve nothing against what is clearly an intransigent, exploitative (in the current climate) management.
And until you grasp the nettle and take on these people, who appear to have every interest in feathering their own nests (if the report of your CEO's grotesque pay-rise is true) while doing their level best to do nothing to improve your pay and working conditions, please refrain from bleating.
