Some jobs or projects have clearly defined boundaries. But many of us end up taking on  responsibilities that aren’t listed in the job description.

This works out fine as long as the redefined job is properly resourced, properly valued, and has a reasonable–okay, feasible–set of deliverables. Otherwise it’s a train wreck.

How do you handle this situation? What language do you use to a) notify your manager that you believe the job parameters have changed, b) set the scene for renegotiation, and c) get yourself a better deal?
