Is it impermissible to eat meat slaughtered in abattoirs because some of the workers there do not pray or curse the religion?

Cursing, when intended as criticism or mockery, constitutes disbelief if directed at the religion of Allah Almighty, whether done in jest, seriously, or mockingly. One who abandons prayer out of denial is, by scholarly consensus, an apostate. However, for one who abandons it out of laziness, there is a well-known difference of opinion as to whether it is a matter of execution for disbelief or as a legal punishment (hadd). If it is confirmed that the slaughterers curse the religion or abandon prayer out of denial, then their slaughtered meat is not permissible to eat, by scholarly consensus. Likewise, if they abandon it out of laziness, due to the strength of the argument of those who consider one who abandons it out of laziness to be a disbeliever.
