Depends on if 1) Did Meta ask him to move? 2) Did they change their remote work policies such that he does not have any other choice but to move? 3) Was he working in Meta India, and being sent on an on-site opportunity, in which case, some prefer to move with their families. If answer is yes to any of the above questions, then yeah Meta is at fault. The person deserves atleast a contractual position till he is able to move back to India or find a job in Canada. Alternatively, he can be compensated to account for the complete disruption of his life. People in India liquidate assets to move abroad. This may be an absolute life changing and costly decision for him and his family.
