I've heard this again and again, that there are no longer any pyramidal programs... But I noticed going over the contracts that programs show you when you interview that they all contain some variation of the following clauses: employment is only guaranteed from year to year and certain vague "minimum standards" must be met in order to be promoted, for example, above a certain percentile on the ABSITE. Maybe this is a dumb question, but how is this arrangement different from a pyramidal program? It seems to me like the difference is in name only, because from the looks of these contracts, it seems like it's relatively easy to get rid of someone and, at least in today's market, where the demand for catagorical surgery positions is high, it's very easy to replace them with someone else.
(Not trying to turn this into a surgery discussion, btw. From discussions with friends going into other fields, this seems pretty much the same everywhere. Just using surgery as an easy example.)
