Is the usual corporate insanity Cambium RIF’ed some of the Regional Technical Managers (RTM’s) after missing financial targets and getting trashed by Wall Street. Not exactly a fantastic plan during a major transition for a lot of customers where the would have bene very useful in taking the load off the CBRS engineering team. Public companies, ug.
