Even more so when that person later loudly proclaims that they never made such a request, even when provided with written proof.
I can of course not say whether the people currently working at Twitter did warn that the recent measures could have such major side effects, but I would not be surprised in the slightest, considering their leadership's mode of operation.
Even as someone who very much detests what Twitter has become over the last few months and in fact did not like Twitter before the acquisition, partly due to short format making nuance impossible, but mostly for the effect Tweets easy embeddability had on reporting (3 Tweets from random people should not serve as the main basis for an article in my opinion), I must say, I feel very sorry for the people forced to work at that company under that management.
I haven't witnessed what happens if the members were determined to anyway, or read up on the circumstances of past wildcat strikes.
Also, the last time I saw something about my local hospital nurses' union in the news, they were alleging that the recruiting and employment of foreign nurses violated human trafficking laws. Basically, they signed people up from another country with a huge penalty if they quit early as "compensation" for the cost of importation.
To me, that strongly suggested the union was not playing a strong hand, when it comes to "unsafe policies".
