laboring

doing arduous or unpleasant work; "drudging peasants"; "the bent backs of laboring slaves picking cotton"; "toiling coal miners in the black deeps"

कोई कंगाल नही होता और मजदूरी करना चाहनेवालेको काम अवश्य मिल जाता है।

My mother had never stopped laboring for me, from my birth to my son's birth.
