Pros
none they will stab you in the back and break company policy and lie to fire those employees who don't fit their vision of the picture perfect employee no matter how proficient you are at your job.
Cons
your chances of making it a career are slim theres a disproportionate amount of employees who arte let go or laid off before their 12 year mark. there is no significance with the 12 years except your about at the cap of what you can make and thats when comcast is about done with you. they are shady and backbiting they can't tell the truth to their customers why would they tell the truth to their employees. they fired me without reason except that its their right being in an "at will" state to fire whom they wished when they wished and i was denied unemployment as well i dont understand why.. i was a model employee with 10 years under me and they left me with nothing to show for it. comcast was my life i practically lived there with all the time i volunteered for because we were short handed and it all means nothing to them employees are expendable to them.
