Robota means different thing in czech than rabota in other slavic languages. Czech robota means corvee. There are different words for corvee in other slavic languages - "barshhina" (in russian), "panshhina" (in ukranian, polish and belarusian, spelled a bit differently in each), and rabota in them means any work, in czech work is called prace.
Edit:
This is a good example of "false friends of a translator" - words in different languages that sound similar but have different meanings. https://en.wikipedia.org/wiki/False_friend
That said rabota and robota still have a common root which means slave in most slavic languages. So how is it the czech is such an outlier is a curiosity.
