  Polarimetry of the narrow-line radio galaxy PKS 0116+082 at the W.M. Keck
telescope shows that it has high and variable optical polarization, presumably
due to synchrotron radiation. It is not a BL Lac object because it has strong
narrow lines, and it is not an OVV quasar because it has no broad lines and the
extended galaxy is prominent. VLA and VLBA images show that it is a compact
steep-spectrum radio source with most of the emission coming from a region less
than 100 milli-arcsec in size. Of the 25 compact steep-spectrum or gigahertz
peaked-spectrum sources measured polarimetrically, four have high optical
polarization. One of these has been observed only once but in the other three
the polarization is variable. This gives an intriguing hint that variability
may be a general property of these objects.
