Tinuiti has lost its way. The company is hemorrhaging talent as senior employees are realizing they can make significantly more elsewhere and are jumping ship. Everyone is completely spread thin and is overworked as a result.
Unlimited PTO is a joke. Sure, you can take unlimited time off... provided you give at least a month notice, train people up on your accounts, work ahead as far as possible, and are OK with the possibility that when you come back from vacation you will be putting out fires caused by the overworked person covering your accounts.
Management is inconsistent and generally exists only to come up with new processes to make things more "efficient" (re: finding ways to extract more work onto employees). Training is essentially non-existent and client documentation is extremely poor. You'll be thrown onto a client and will be expected to pick everything up in a few days. There is very little growth - client-facing employees will almost always hit a ceiling of where they can advance to. Management recently "updated" job descriptions across the board to give junior employees more senior responsibilities, of course while maintaining their junior-level pay.
If you are client-facing, you will work late nights, weekends, and holidays. That would be manageable if the compensation was competitive, but it's not. Everyone I know who has left in the past few months has gone on to work in-house doing pretty much the same job while making 50% more.
