<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
The other day, I was talking with a slope-construction worker I've known for a long time.<\/p>\n
He says he\u2019s gotten noticeably older lately and has lost his strength.<\/p>\n
It seems he hasn't been out on site much either, but,<\/p>\n
Anyway, I just need a job.<\/p>\n
I heard that since the start of January, orders in the Tokai region have been a bit slow, and there are plenty of slope-construction contractors with excess capacity.<\/p>\n
Since we, as public works contractors, rely on contracts from local governments for our work,<\/p>\n
It's hard for us to generate our own work. There really aren't many private-sector construction projects, are there?<\/p>\n
When the national budget is drastically cut, construction companies will also downsize.<\/p>\n
Are there any slope stabilization or anchor installation contractors available in the Tokai region?<\/p>\n
If anyone knows of any contractors in the Tokai region, I hope we can reach out to each other and help one another out.<\/p>\n
But that's beside the point.<\/p>\n
