Replace # with .
I think that you should find answer to your question here: europa#eu/index_en.htm
Here ec#europa#eu/immigration/tab1.do?subSec=30&language=7$en they say:
Rules for certain categories of non-EU residence permit holders
Certain categories of non-EU residence permit holders, and their family members, may be able to move more easily from their host EU country to another EU country, where both countries have adopted applicable EU rules.
Highly-qualified workers who have an EU Blue Card, long-term residents, researchers and students who hold the necessary residence permits may also be able to travel to another EU country under certain conditions.
So it seems that you may travel, but am not sure about work.
You may also send question to Polish embassy in Prague: www#ambpol#cz/eng/index.html or consular www#ambpol#cz/eng/konzular.html or ask personally If they don't answer email.
You can also ask embassy of your country in Warsaw per email.
