Hubby got retrenched for redundancy after announcing pregnancy

Hi fellow mummies, my hubby just got retrenched by his company for redundancy.. and this is after he informed his boss and hr that we are pregnant. his last appraisal 2 months ago went well so there shouldn’t be any performance issues. his company has so many PRs but they let go a Singaporean.. anyone has any advice if MOM will step in regarding this? thanks in advance.
