Pros
Overall, I'd say OneDigital itself isn't a horrible place to work. However, your experience there will very much depend on the management team and micro-culture of the group you work within (meaning, the area of the country as well as the "vertical" you worked in, such as retirement, benefits, HR, or sales). "Unlimited" PTO for salaried exempt employees is nice, but depending on your team you might not really be able to take time off.
Kontras
OneDigital has grown rapidly through M&A in the last few years, so the company operates in a very fragmented manner. Speaking for the team I was on, there was a LOT of micromanagement and insecure leadership. Additionally, there were a number of really high-performing employees who were there one minute, gone the next, which doesn't instill confidence. From my perspective, your success (or lack thereof) was almost entirely dependent on how willing you were to suck up to the management team in your area. I would say you REALLY have to be willing to "drink the Kool-Aid" if you want to do well there. It's interesting to notice the trend in the last few years with regard to OneDigital reviews. When I joined, the reviews were overall very positive, and the CEO had an approval rating of about 4.8%. Now, the CEO's rating is 71% and only 52% of employees would recommend OneDigital as a good place to work? Seems like the company is on a downward trajectory. I even had a former client tell me they'd be shocked if the company was still in business a year from now (though I suspect they were just talking about my team, not OneDigital as a whole). While I would love to be able to applaud the culture and values of the company (which are very good on paper), the simple truth is that my team really didn't follow those values. While I was enthusiastic when I first joined the company, I quickly lost hope that management would take any action based on the feedback they received. One of my biggest frustrations was the lack of feedback from management on how to be successful; there were poorly defined metrics and no real formal performance reviews, so it left team members floundering.
