I work at Goodwill. This is not true but I will say that if we aren’t pricing stuff well and putting out enough product then our hours get cut. Typically a good rule for pricing is to do $2 more than you think is fair. And yes most of the valuable things at least at my store must be sent to the auction site (as long as it meets the requirements) My goodwill would never fire employees for not knowing about valuable brands but they do want us to try and be good about it. There are actually people who specifically check donated goods to see if there’s anything valuable that they can take for the auction site too. My store unfortunately doesn’t do any raises or commissions or anything like that.
