ABSOLUTE WORST CUSTOMER SERVICE EVER!!! They don't respond to you in a timely manner. Even if you're on a job site you can't get ahold of a real live person. I love the concept of shiftsmart but they have a lot of work to do to be a successful company. It's terrible knowing that you worked your shift and you're not getting paid for it and there's nobody you can call or speak to about it. They do have phone numbers but nobody ever answers. It's really really bad!
