Literally EVERYTHING.
The management is extremely selfish. They fire people based on personal grudges. The company barely has a vision for the next 2 years. They do not understand the concept of a work-life balance and do not even make an effort to be empathetic. In times of crisis, you might want to turn to the HR, but even the entire HR function is too loyal to the business and will turn a blind eye to you. I suggest do not waste your time trying to set things right. And if you want a great career for yourself, never let SignEasy even become a pit-stop.
