Nov 12, 2021 Report
BROTHERHOOD? HA! I informed my former teacher John F. who was on layoff at the time that my division(sign division) was very busy and he should consider working there. I explained the pay is slightly less but you drive to a shop, take a company truck and gets a fair amount of overtime. He spoke to my delegate Kevin S. and the next day he was at my shop. Since signs is a specialty that isn't taught in the IBEW schooling I had tu TEACH my teacher how to wire up neon signs. THAT SAME DAY I WAS LAID OFF. WHAT KIND OF BROTHERHOOD IS THAT. HE DIDN'T EVEN HOLD A CARD IN MY DIVISION. BUT BECAUSE OF WHO HE KNEW HE WAS ALOUD TO STEAL MY JOB. WHAT A JOKE THIS UNION IS. FACTS AND I'LL GLADLY ANSWER ANY QUESTIONS THE LOCAL IBEW 25 HAS. IF THEY DARE.
