I was exactly in the same case. (Fortune 100 company etc.) My experience is that the only reason you do not get money is that your managers are too lazy to get compensation arranged with HR. As far as HR is concerned, they could not care less whether you receive naught or the exponential of your salary as compensation, the only thing they hate is they have to sign additional checks, and "setup a procedure" which seems like a lot of work to them... Negotiations with HR definitely leave a Dilbert aftertaste, so, be patient if your manager needs some time to get anywhere. As a matter of principle we arranged that only team leaders or project managers would get the pager before the agreement was reached, got everyone's motivation aligned. Team leaders got compensated, but not PM as they participated to the negotiation. About seeking legal advice... sounds very expensive, as hiring a lawyer will very probably at least get your bonus cancelled. This is true if, as in my case, you start having to support something, if you are in a group where such thing always existed and never was paid, do as everyone in the group leave, or if you love support, tell your manager that is the only way to have a decent "retention level".
