Low pay, bad working condition, no sense of accomplishment, hardly any upwards mobility. Why would I do that, if I have better options?
I kind of agree with the lack of career options for factory workers, but in many factory jobs there are several upsides.
For example many places allow you to listen to music/podcasts all day, while you are working. The work itself is often not mentally taxing and it doesn't follow you home when you leave. Also there is no reason not to feel pride in being able to complete relatively complex tasks with care and speed.
To me it seems that the same "carefulness" is being exercised in the counteroffensive. AFAIK majority of the reserves aren't being used. Maybe the government is concerned about the repercussions that a failed counteroffensive could have in terms of the long term support from western countries. In such case they would have every reason to be conservative when doing maneuvers and letting information go public.
What I'm saying that in our world appearances matter (arguably too much), and Ukraine is stuck playing a game to keep foreigners happy. Also note that I have no merits to back up any of these thoughts and I'm pulling them out of my behind.
