我是工会的一名宣教干部，经常进行职工思想状况的调查，通常采用的办法是抽样调查。由于时间紧、人员少，有时到企业找职工开个座谈会，或者找领导谈一谈，甚至随便找些职工聊一聊，认为这样调查既省时又省力。请问这样搞调查行吗？（山东临沂市王刚）王刚同志提出问题，反映? I am a propaganda cadre of a trade union who regularly conducts surveys on the ideological condition of workers and workers. The usual method is to conduct a sample survey. Due to the tight schedule, fewer staff, and sometimes to find a job for enterprises to open a forum, or find leadership to talk about, or even find some workers chat, that this investigation is time-saving and effort. Excuse me, is this investigation? (Shandong Linyi Wang Gang) Comrade Wang Gang raised the question, reflect?
