You seem to put in much more than you get back. I saw people who shouldn't have even been employed move up the ranks within management and then wonder why employees have low morale and are dropping like flies. While the company may preach "work/life balance", it's more like something they can put on paper to look good but will never really have to implement. Rather than invest money to replace an employee who has left the company, they will find ways to redistribute work amongst those who remain who may have already had full plates to begin with. Yearly salary increases are not based on merit, in fact, you're lucky if you receive a salary increase to cover a cost of living increase. Lucky.
