The Supreme Court recently in the month of August permitted a widow to continue with her job which she got as compassionate appointment despite her remarriage. This was done though the rules were to the contrary saying that widow's compassionate appointment be terminated upon her remarriage.
The only condition the Court had imposed was that she'll have to contribute 50% towards her children from her deceased husband.
Likewise, as long as you're ready to maintain your mother in law, there should be no imped for you as well.
