汚水を流されながらの配管更新…「スゴく大事なお客さんだから強く言えないんだよね」が監督の言い分ですが、どういう意味でしょうか？流されながらの養生・撤去・接着・仮繋ぎ・掃除まで、倍の時間がかかる上に完璧な仕事なんて出来るわけがありません。大事な人に半端な品質を渡すのは矛盾してます。

@kojikojikodayo 売上が大事なのは事実ですが、社員を大切にしない、向き合わないのは論外だと思ってます。個人的には、そういう経営者からは出来る限り早く離れることを考えます。人生にとってマイナスの面が大きいわけですから。

高速を使えば片道1時間かからない現場に、毎日下道で2時間以上かけて通う人がいるのですが、全く理解できません。なぜなら時間の価値をわかっていないから。往復の2時間分の差を作業や資格の勉強に当てたり、家族や恋人と過ごしたりする方が、幸福度も高く結果的に高速代の何倍も稼げると思います。

タジマのセフコンベ（専用のホルダーにガチャっとはめられるやつ）を愛用していますが、新しいものを買う度に解せない点があります。それはホルダーが必ず付属していること。ホルダーの方はあまり壊れずどんどん余っていくので、300円くらい安いホルダー無しバージョンみたいのが欲しいと思ってます。 pic.twitter.com/EUNodLbMsn
