In situations where you notice someone experiencing covert racism i.e. being passed over for promotions at work or receiving unequal service in a restaurant, you should consider taking action. You may consider asking the individual being mistreated if it's ok if you spoke up. They may decline and that's ok. They may decide that they don't feel safe enough to manage the backlash that may ensue if action is taken. If they accept your support, consider taking action by using your position to help challenge the racist act.
