Jenny on the job: Has her fun after work

This wartime Jenny on the Job poster could be taken more than one way, ie., don't forgot to have fun after work, or don''t play around at work.  I'm pretty sure, based on other posters, the former is meant.

This is a U.S. Public Health Service poster and there was wartime concern that workers engaged in long hours would forget to have any downtime at all.  That was known to contribute to poor health.

An irony of this is that workers of the 1940s likely tended to be a lot more social, and have more fun as a rule, after work, than they do now.  As the author of Bowling Alone has gone into, Americans have retreated over the years into their own homes and lives and, save when they're young, and not even as much with the young as in former times, they don't get out nearly as much as they once did.  This has resulted in a lot of former institutions disappearing over the years, such as fraternal organizations.

Not all of those old habits are really missed.  For example, the once common gathering of some blue collar men at the bar, where they spent the whole evening, is something that's gone by the wayside and that's probably for the better.  And of course a lot of people do have a lot of out of the office activities they engage in.   The U.S. Public Health Service wanted to make sure that workers of the 40s were getting out there then.
