Weird, there's hardly any mention of this in the news. I remember working for Verizon management and waiting for my number to come up during one strike in 2012--then being forced to go to "scab training" so that I could learn to climb telephone poles and repair lines hundreds of miles from my home. The pay would've been insane, but luckily for me the strike ended before my training was finished.
Similar experience, worked for a major computer company (not IBM), as a field engineer, i.e. maintaining mainframes and adjunct equipment such as high speed check sorters that were in all the Federal Reserve location and major banks. Later transitioned into the next big thing, networking.
NYC was one of the few "union" areas, and when they threatened to strike and having been promoted to a management position, told to prepare to go be a scab. Likewise, pay would have been insane, but fortunately the strike was settled before they actually went out. Didn't really fancy a 3–4 week tour of duty working as a scab in Manhattan, where my skill set would have sent me. This was in the mid 90s.
I knew guys that worked 3–4 weeks on, 2 weeks off, then back for another 3–4 weeks for up to 8 months during previous strikes.
I was never union, and had a good job, pay, benefits, etc., and didn't feel the need of a union. I had in demand skill sets in the industry, and could easily transition to other companies, both large and small. Even turned in my notice a couple of times only to be offered incentives, in writing, that I would have been a fool to ignore. Bottom line, it allowed me to retire at 55, and 24 years later... no regrets
