SP, I would agree with your IC... Your W is currently "unable" to see the value you brought to the M...
And unfortunately, until she "opens her eyes"... there is nothing you can do to "show" her... and going on strike is unlikely to have any positive value, either...
As much as you want to be appreciated regarding how you've contributed... in what way will it help your M? Will it hurt, help or have no effect?
If it will hurt (because your W just won't agree / see / admit your value; therefore it hurts you and your ego) then don't do it...
If it will help...? Well I guess you can try, but I'd recommend not doing anything twice if it hurts the first time...
If it will have no effect... is it worth focusing on, or is there something else that you might do that MIGHT be helpful...?
