You scared the **** out of me when I saw your subject line "frustrated road tech ready to make a change?"

I started thinking "How's he know what's going on in my head"????
Then I read your post, I really feel where you are coming from right now.

You come home every night feeling like you're the worlds whipping boy and everybody took a extra large crack at you today.

I cover 8 counties and have over 200+ trucks in my A/R, some customers treat me like family and I bend over backwards to help them and have been toe to toe with the service manager for them too, others treat me like I'm something wet & slimmy that was clinging to the bottom of their shoes, and feel it's their right to walk all over me when ever they get a notion.

The wife has told me a few times to just call in and tell them to come pick up my van & uniforms, but like you I just can't go out and find a job on a moments notice with the pay & benefits I currently recieve.
Ever heard the saying "Same ****, different shirt", that's all you'll find if you go to another lift company. The grass isn't always greener as I have found out.

I had over 3 years as a road tech with a small company in Ohio that was home based out of Alabama, We saw the company President maybe 3 times a year, The week I had my resignation typed up and sitting on the dash of my van and ready to turn in, we were all called into the shop and it was announced that our branch was being bought out by another larger company, That was 5 years ago.
I kept my time and vacation and got much better benefits with the new employer only thing is after all this time we still feel like we're the "Red-headed stepchildren" of the company and not a real employee of the new company.

I've had 8 customers within the last year either offer me a job or tell me when and if I go out on my own or go to another lift company they'll come with me. That just makes me work harder to keep them happy and do what I can to keep their business.

Right now everybody is hurting for business, and managers are learning new ways everyday how to mess with your head and what buttons to push to make you mad enough to quit, it's what they want, I found out 1 thing a long time ago, We're all replaceable. There is plenty of people who would be happy to step into our shoes for less money and tell the managers 'Thank you sir, May I have another??".

Talk to your General Manager off property, make him take you out for lunch or dinner and let him know how you feel.
Don't accuse or point blame at any one issue or person, be consructive and positive and let him know you want more from the company and your ready to grow or go. If that doesn't help, contact your HR people, it's your right and that's why they are there.

The past few years the company has been on this big push about PM compleation and new PM sign up's even though they will turn around and whine that it's a money loser. I am so sick of spinning oil filters I could puke, I knew it was about time to start looking when I did a complete PM on a I/C truck with my eyes closed. I even started to do PM's different ways or try to do something different just to keep my sanity.

In todays economy I would be careful of shopping with competators, We work in a small close knit industry where bad news,rumors and gossip always travels twice the speed of a "Atta Boy" or a "Thank You".
Many employers will fire you on the spot these days if they might think your talking to the competition or one happens to call for a work reference.

We work in a VERY stressful and thankless job, sometimes I feel almost like a prostitute with a pimp for a service manager. Sit down sometime and think how much both jobs parallel each other. It's stunning when you write it down, then you realize that a good prostitue make 3 times as much money as we do.

Take a few days off if you need to and gather your thoughts, then talk to somebody that can either help you find the answers you seek, or at least help you unload your van.
