Some People Can't see a Good Thing if They are Standing on it !

Why is it that there are always coworkers that try to make out that your employer is always out to get you? The Company i work for has been around for 20 plus years, But coworkers act like they are just getting started and have no idea what they are doing. I worked for this company when i owned my own truck and they have always treated me very good. Now i work directly for them and still find that i am treated very well. There are some however that call them crooks and thieves and say they aren't concerned with anyone else but themselves. Not true , if 1 of our truck have a breakdown that they cannot get fixed that day they will let you take a company vehicle home rather than call for a ride home as long as there's a vehicle available. They are very fair in their pay and always making sure there is work available in advance. I find they are one of the last companies to shut down in the mud season and try to be the first to start up again or to not shut down if they can help it.The other coworkers fail to see this i guess and just look for things to complain about. I'm not sure if it makes them feel better about how good they are or what the reason is but it gets tiresome listening to this day after day about how picked on they are,Oh well i guess there are some that are like that no matter where you work.
