I don't think that an excuse that the client wants it that way is workable. After all, where are the clients going to go--CoRI? Other MSing companies are probably in the same boat, and clients have to deal with the industry as is.
I think that MSPA shoppers or some group needs to make a list. That list will group shops from easy to hard to specialized. An easy shop might be run in, get a receipt, run out. A medium one would be ask a question, then write a narrative, or having to go back to the store for a return. A hard one would be going into the outdoor store where nine departments are visited or the home supplies store where several transactions are observed and employees talked to. There could even be a hardest shop listed. The specialized ones require something, such as driving a specific car, having a specific education such as a college degree or a mechanic's certification, or having skills such as portraying a high-dollar customer or speaking a second language. The time required to do the shop should count towards the pay as well.
No more of these excuses: "This is a fun shop!" or "You get to eat at your favorite restaurant." In addition, mileage should be spelled out as so many cents per mile, instead of an added fee that we can't calculate in our heads when we feel we have to hurry up and grab it. There could be a basic addition for miles when we, for example, leave our own zip code.
This group (us) should place a price range on each group of shops for the companies to consider. I think that these shops ought to pay at least twice what they do now, and for some, three times the amount.
Any shop requiring special equipment, such as a camera, ought to pay more. After all, the person with the camera should have special skills. Not everyone can take a good picture.
We also ought to promote a certification for ourselves that most companies will honor.
We shouldn't have to spend hours filling a day of consolidated trips for this piddling amount. We should be able to freely add shops to our trip to make a better living, not just to make the trip worthwhile.
Some of us have other jobs. Could we just sit this out until the companies cough up? The only way that would happen is if they don't have new shoppers to add to their stable while we are waiting. Anyone can shop. We do it in our daily lives. But, as we all know, not everyone can shop and get a 10.
I'm not advocating a strike. We can't do that, anyway. I'm advocating a professionalism that even the companies recognize. How can we make them feel guilty for what they pay us?
