You earn a 2nd week of PTO only if you've worked there for 5 years. The 401k match is awful.
Upper management is clearly hungry for profit, which would be fine if the company valued it's employees more. Life Time says a lot about "being the best" in the training industry, but the company has done little to actually ensure that trainers know what they are doing or can make professional recommendations based on client needs (it's hard to recommend something when your paycheck depends on selling training). The best trainer in the world could fail at this company because if you aren't making money for Life Time, you aren't making any money. Furthermore, there is no quality assurance or really any set standard for the quality of a training session.
There isn't much career opportunity if income is your main focus. The company is expanding rapidly so there is room or advancement, but most promotions mean you have another product to sell. There should be opportunity for management roles, but from what I've seen corporate puts too much on their plates for them to be effective in their role.
