to all new techs , i would worn you there are some employers that take you for granted . ths is one persona l experience from my book
I work for a service company where the boss likes to penalize the employees for not covering the previous techs mistakes
I was sent out on a job a couple of months back to take care of a leak in a refrigeration system.
the leak was on a couple of flare nuts no biggy right well the tech that was there prio9r to me had no bussiness with a torch his brazes looked like lava but since i found no leaks and didn't want to recover the refrigerant to fix his slop i signed off on the job well the next time there was a problem with the system guess who got it and it hurt my pocket book cause i spent 5 days redoing his slop and didn' get paid for it .
and that is not the first time he has done it but when you like your job what can you do.
