こんな悩みを抱えていませんか? 社員のモチベーションが維持できず、すぐに辞めてしまう。 事務所が国内外にあり協力会社や派遣社員も多く人材を把握できない。 チームワークを高め、効率的な組織運営につなげたい。 ウィリズムは社員の気持ちを蓄積し可視化することにより、組織、社員の生産性向上に繋げ、これらの悩みを解決することを目指したモチベーション・マネジメントシステムです。 心理学者のショーン・エイカーは、ポジティブな気持ちで仕事をする人の生産性は、ネガティブな人より31%向上するといわれており、現状に対してポジティブになることさえできれば、脳はより熱心に、速く、知的に働きその結果としてより成功するようになるとの結果が出ています。 2014年6月「労働安全衛生法の一部を改正する法案(通称:ストレスチェック義務化法案)」が国会で可決・成立したことをうけ、社員50人以上の事業場に対して年1回の労働者のストレスチェックの実施が義務づけられることとなりました。 「2011年特定非営利活動法人しごとのみらい 」調査 結果では職場で悩みを抱えている人は全体の80%、仕事の悩みを本当は上司に相談したいのにできてないのが実態です。 これらの課題を解決するためにWillysmは非常に効果的なソリューションです。
