  We examine a few families of semistandard Young tableaux, for which we
observe the cyclic sieving phenomenon under promotion.
  The first family we consider consists of stretched hook shapes, where we use
the cocharge generating polynomial as CSP-polynomial.
  The second family we consider consists of skew shapes, consisting of
rectangles. Again, the charge generating polynomial together with promotion
exhibits the cyclic sieving phenomenon. This generalizes earlier result by B.
Rhoades and later B. Fontaine and J. Kamnitzer.
  Finally, we consider certain skew ribbons, where promotion behaves in a
predictable manner. This result is stated in form of a bicyclic sieving
phenomenon.
  One of the tools we use is a novel method for computing charge of skew
semistandard tableaux, in the case when every number in the tableau occur with
the same frequency.
