Don't join ATS. It will put them in an awkward place. Many are on to the scheme, that's why no word on it yet. They need more time to package it up in legal terms. They are counting on techs biting the proverbial carrot.
They need the option to scale back. Altice has taken on too much debt, too fast. Look at the signs. Altice uses 10 year bonds at low interest. So they only pay interest. Once the time is up they need flexibility to sell off to pay debt. Their focus is making massive money, reduce the need for paying high salaries, benefits, etc. ..
So many people are cord cutting. Numerous websites highlight ways to cut cable TV, and keep Internet only. Networks are demanding more money for cable providers to carry. Cable industry is changing. With FTTH, techs become, " on-demand technicians", contractors.
Altice is losing the battle at SFR/Numerical.

Previous optimum owners tried to focus on customer service. That's how you value paying higher price. These new guys don't care about customers. Bad morale from employees will not promote good service. Keep employees happy and they become ambassadors, advocates, for the company.
If all of the Techs including Construction, OSP, don't sign with ATS. It makes it very difficult for ATS to form. And it makes it harder to scale back techs. You can do FTTH as you are.
They can't make it seem like massive layoffs. Sadly, it will only buy you some time. Some more time is all you need to plan better for a change of circumstances.
Plan now. Pay down debt, don't be like Altice and take on more debt you can't handle. ATS is a global model to standardize cuts, in order to keep option to scale back the work force.
Altice can be a great force in the US cable industry. Their investment needs to be in balancing and offering customers what they truly want, pick what they want, reliable, fast Internet, and the greatest customer service the planet has ever seen. The latter means they have to retain current employees. Have employees feel needed.
But again, that is just a dream. Greed clouds reasonable judgment. The same greed that Altice has, is the same as a busted gambler. They scavenge everything they have, for one last hand. Pa*ck Dhi is obsessed with fiber. He is obsessed with property and high life. His minions are of the same mindset. If they don't change the business model, they will fail. That means danger for current employees. Plan.
Don't sign on to ATS. It can be done without ATS. Put them in an awkward position. Union may do that. But I'm not sure it will be enough. It's too little, too late. Should have done it, 2 years ago.
