The call schedule for their program is going to be fucked from Day One.

Female interns that I knew purposely planned to get pregnant during the first year of their residency once they are matched and locked in.

Surgical residents can't be replaced during their multi-year residencies and are relied upon by hospitals and attending surgeons as a slave class of cheap labour, overnight call and billings.

Normally, if a female intern ducks out for maternity leave, the rest of the interns are just expected to work more and take more call to pick up the slack.

But that doesn't work if 11/12 of your roster is theoretically unavailable at some point of their contract.
