Because really, not many employees are going to remain engaged if there isn’t much in it for them. If they sacrifice and put in the emotional work of being a fully engaged employee and doing the work that helps the company succeed, there’d better be more than a yearly 2% raise and a pizza party to celebrate. Especially when Don in the cubicle across from them left at 5 every day, did the bare minimum to keep his job, and got the same 2% raise. There had better be a path forward for all the hard work, otherwise, they’re just wasting time and effort here.
