This depends on what you mean by a glass ceiling. There is clearly something going on that causes there to be fewer women in upper management than are in the workforce as a whole. If that is all you mean by a glass ceiling, then there clearly is one.
However, if you are asking whether discrimination causes the glass ceiling, the answer is much less clear. It is very difficult to know why there are fewer women in high positions, especially in a time when no one is stupid enough to say that they discriminate against women in their hiring. It is hard to know if there is prejudice against women or whether it is something else (like women failing to move up because they take time off to have children).
