A Company Alumnus Social Media/Networking Service

There should be a website/app or platform that would connect/reconnect companies' with current and former employees for the purpose of celebrating and establishing or solidifying camaraderie among each company's alumni or the whole of those responsible for the success of each company. 

...The prescribed would be similar to Classmates.com. Employees would be listed according to the year(s) that they are/were employed for each company. Once listed, connection requests would be sent to each employee or former for which each company has contact information. Once they accept the requests, they will have officially joined the stated platform...

Popup advertisements would otherwise be exhibited to individuals with the precise names of former employees for whom companies do not have contact information. These popups would include queries about specific companies seeking their alumni, i.e. "Are you Jane or John Doe formerly of XYZ company. Yes or No???"

If the queried individual is the subject alumni of the given company and selects Yes a link would be provided to them in the pop up ad directing to instructions on how to join the company on the company alumnus social media/networking service or site. The web address to the site would additionally be provided to them.

Every company in the world should join said platform and add all of their current and former employees. Former employees would too be capable of sending requests to join to their former employers. 

It would, of course, be up to the current/former employees whether they would accept requests from relevant companies and up to the companies whether or not they would accept requests for any given former employee...

The companies could plan periodic or routine events/reunions inviting all of their alumni. They could have commemorative t-shirts and other promotional products made for attendees. 

They could retroactively honor employees/former employees who are deserving of it and generally recognize personal accomplishments of employees/former employees outside of the companies. They would take lots of pictures to post on their alumni platform and for optional publication in the companies' year books.

A company alumnus social media/networking service would essentially rekindle friendships. Co-workers/former co-workers are more like family in many instances. The prescribed would allow them to network, reconcile where applicable, and catch up with goings-on in one another's lives and to support one another in their endeavors. 

The prescribed would improve morale and productivity within companies; it would lead to greater success for employees/former employees and for communities and government.
