Workers join the Union

[mean35]

I need help! How come the it takes forever for me to build anything later on in the game. It says its estimated time is like 10 days and in reality it takes about 50. This only happens when i hit around day 300. Do the people that work for me join the union or something and refuse to work lol ....am i missing something?
