Glassdoor is a two way street, as it also helps employers. They often highlight their positive rankings. I also am familiar with cases where employers force current workers to leave positive reviews to skew the rankings in their favor. Just like any review mechanism, it’s fraught with issues.
I forget what it was called, but there was even a short-lived effort to create a review site for other humans, so could look them up before going on a date Needless to say, it gets complicated very quick, and is full of opportunity of abuse and little recourse if you’re on the loosing side of a review that wasn’t objective, and someone wants to get even with you. Think of all our ex-spouses… Or people getting swatted. What if that client left a review about you saying your work sucked? You may disagree, but if you get fewer calls, what are you gonna do about it? How will you clear it up so it doesn’t haunt you for the next decade?
Another aspect is that reviews generally are not great without a large sample. Like a gmask tracker with too few points, or points too close together You need a lot of them before you have statistical significance (which in any small industry is hard to overcome). Add to that, that most people are prone to leave a review when they’re upset about something, but usually can’t be bothered about a neutral or positive review, unless someone reminds them or bribes them.
Lastly, in many cases both parties contribute to the issue at least to some extent. How do you know that the issue wasn’t miscommunication or incomplete expectations? Sometimes people are eager or need the job to pay the rent, so they’re reluctant to ask questions or put up conditions and boundaries in fear of losing the job. Or they don’t know yet what all to ask and clarify. And then they hope for the best or assume. Easy traps to find yourself in as solo operator, because you’re both the artist, the salesperson, and the business manager. You can’t play good cop/bad cop if there is just one of you. That’s where big post houses have an advantage - they have hard-nosed folks that make this stuff non-optional, and brands that allow them to play hardball more than most freelancers can.
Even a hard to work with client like the one this thread started with, can be fine to work with if you go in eyes wide open, have a good contract template, a lawyer on hand, and enough cash flow that Net 90 terms aren’t an issue, and you build that into your rate (just add 3 months standard interest rate to your quote, and they essentially borrowed that money from you instead of the bank). It can even be good business to service these tough nuts, that no one wants to work with, if you set it up right. Consider it combat pay.
Which by the way can be a way to get paid faster. Write your contract that states Net 90 payment terms and silently up your rate by 10%, and then offer a discount of 10% for faster payment. It’s essentially reverse interest rate. And some companies have rules that they must take advantage of such discounts. Make them the suckers.
With all that, it just seems like it would make you feel good, but not really be helpful in the big picture.
One thing that should always be possible in a forum like this, is that if you have a new client and make a big bet, go ask here if someone else had worked with them before and could share their experience privately. That’s easy and stays clear from trouble. In some cases you can even ask a client, if you can speak with someone else they worked with before for a reference. Now the cheap skates or those that know they have an issue, may refuse, and that can be a yellow flag in itself.
