Am slowly being drained of ambition because my talents and sacrifices are not valued or compensated adequately.

Division of labor, diversity of talents

Sales team is not cohesive, different rules exist for different employees

Lower their voices when in the office, the yelling from office to office to have simple conversations needs to stop. They need to be considerate to others.

Know boundaries, be respectful of others (no loud obnoxious banter in the office, etc), take more pride in their work so that it helps others do theirs. Communicate with each other often and promptly.

Management needs to improve their oversight and recognize those in crisis. They also need to recognize there is a human behind all the work that gets accomplished out and how that work affects the employee physically, mentally, and emotionally.

Two decades of work experience at the business should mean something during consideration of promotions. There's an element of nepotism that exists that precludes admin staff from advancing beyond their starting position. Non-sales/Ops incentives are gone. Pay bumps not following add. duty or COLA.

Actually care about the safety and wellbeing of all your coworkers and subordinates instead of just saying it to Ops in a safety meeting or on a kiosk. Follow corporate guidance on safety in teams, better strobe lighting on trucks would improve the appearance that management cares about your safety.

I do many tasks around here that no one else can/wants to do, and I've never been given any incentive/pay increase, other than keeping my job, to do them. What would make me feel better is to actually pay me for every new task you assign me that they didn't hire me to do.

As an admin employee, neither management nor your fellow coworkers are interested in your success. They see you as a tool to use & exploit to ease their workload with no regard to your burden. So when you now play assistant to a number of salesmen your product and mental state suffer as a result.
