Many many years ago. Worked for an outsourcer
The client had been given a custom support soluttion (one SD - "T", one account manager, and agreed to a deputy SDM on each site. On the technical side, remote 1st line helpdesl, on site 2line support, and a centralised network/server team. I owned the IT, T owned Service Delivery). This was the customers preferred structure, lean and agile. It served us well as we doubled the account value within a year, taking on more and more IT services
Long story short is our boss had a heart attack, and the company replaced him with the 'standard' service management template: 5 managers, including David, a "technical director'. Although I owned IT, I was still just a "manager", or glorified techie team leader. Long story short, I quit as I had effectively been dismissed.
Now we, with our peers in the clients network team, upgraded from a flat Token Ring environment to a routed IP environment with switch 100mb ethernet on sites. Cutover was scheduled for the last weekend in Oct. That Friday, I was asked if I could assist over the weekend and be available Mon and Tuesday by "I", my client-side peer, and "G" one of my guys who was managing the work. I agree a daily rate with "I" and stress to G he needs to run this past David, who agreed. I duly attend
Thursday I get a phone call from him asking why I am not in work. and what is this invoice for £6000? When I remind David I quit, he replies "i never processed your resignation, you are still an employee". nope, I start a new role next Monday. I also have a mountain of O/T that needs paying, and almost a full years worth of hols owed. Now I had also handed over a lot of documentation to David with my resignation letter. Turns out he hadn't "nor processed it" - he had deleted it.
A month later I am still getting calls from him, demanding I turn up to work, I provide information I no longer have, etc. Eventaully, two months later, chasing up unpaid OT and hol pay (and I am still being paid by the company!) I end up on a call with a very senior manager. I ask if the issue is malice or incompence? He asks whom the manager was, and when I reply "David C" replies "The later. CBU [client] had him removed from the account".
My invoice was paid. My OT was paid. My pay-in-lieu was paid. And i kept the two months pay I received after I left. They did invite me back to join Professional Services... yep-no.
This was 1998. I wont name the companies as whilst the outsourcer has gone, the client still exists. One of the best clients I have ever worked with.
