Anyone told and/or made to use Yammer or Facebook workplace to 'stay in touch' with corporate communications from on high ?

No, certainly not.

I am now retired but my employer would have never done anything so stupid.

If for any reason they really needed contact anyone out of hours or premises, they would have used a telephone or perhaps e-post. This may have been necessary occasionally for staff working away from base, but only for genuine reasons connected with the work or the individuals.

"Corporate communications from on high" might be important, but most can wait for the employees' return to office. Very few are urgent.

Further, company communications, nationally, site-only or department-level, were always [i]only [/i]on the company's Int[i]ra[/i]net. Not the Internet, certainly not via Facebook or its ilk!

Edited because:

Having posted the above I realised I had never heard of 'Yammer', so looked it up. Yet another application developed independently then bought by Microsoft. Presumably to further MS' monopoly and data-harvesting business!

My work uses those things, and my work also tries to make all staff accept a company supplied smart device that is pre-loaded with company apps for email, etc. but I refuse to accept a company phone and only ever look at work email at work logged into a computer terminal.

I do a very minor bit of communication with my boss about stuff directly related to me through my personal email account but still usually during or closely 'hugging' rostered shift times. Never on days off.

That's the best way, as the old saying goes, we work to live not live to work

Yes. Then I was bullied, mobbed and fired pretty quick.
I was overheard telling a coworker that she was allowed to turn off the phone if her family wouldn't stop calling I said,"it's not a remote control for your body so your family can use you from a distance,". Something was recording me.
My boss quoted that and said it was my last mistake - pretty much the last straw.

Eww 🤢
