Back in the day there was no email and my two days off were in peace. When there was ccmail I came back from my weekend to read over 100+ emails in the first morning. With iPhone / smartphone employees like myself when not working are reading replying texting calling fellow peers and bosses in our off time . It is not mgrs owning employees, it is employees willing to work for free so to not get behind in what is happening day to day.Regardless of Jokes. The risk is real.
There are groups that try to weed out people who "make the company" look bad on any social media.
Unsure how bad some companies have.. but I've heard horror stories... from companies that refuse to separate personal life of the workers vs them on their paid hours.
I mean, I've seen managers that think they own the employees 24/7/365
