No, pregnancy disability leave (PDL) does not end at childbirth and may extend beyond the date in the original doctor's note. PDL protection covers pregnancy, childbirth and related medical conditions and, therefore, extends until such time as an employee is released to return to work by their doctor.
It is important to keep in mind that the date specified in a doctor's note taking the employee off work is not a firm date but an estimate of how much time the employee is expected to be off work. For employers, that date often is used as the date that the employee will either return to work or provide another doctor's note extending the time off.
