Of course, only after having established evidence against the individual which speaks to the actual reason they were fired; they wouldn't want employment regulators to get the impression that the termination of employment was in retaliation to these valid complaints. More seriously, if one wants to make a stink about this sort of policy, this is what they need to worry about. I don't want to tell someone they're wrong for choosing not to worry about this and, in OP's case, accept the inconvenience of using a landline for 2FA.
