The layoffs will only end when all of the experienced, veteran, "high-priced" employees are replaced by cheap workers who will work at the new hubs. Remember, these are not real layoffs, they are "replacements". The work is still there, it is just the cheap employees who are going to be doing it instead of the "expensive" employees.
That's right, people can work hard but companies can terminate them for any reason, no matter how hard they work or how valuable they are. There is no loyalty toward employees.
Perhaps ADP has not lost its core values (making money), but it has lost its mind in replacing valuable employees with cheap, inexperienced workers who are not motivated to succeed. The company is in a downward spiral.
Perfectly said by @UlrZNXy-bet.
