There is so much misinformation in the comments on what Molina does and doesn't need to report. In California ,Molina MUST, under all circumstances, report the titles, and number of employees effected by a mass layoff to the state as well as to each city where the worker reports. For most remote IT employees this would be 'Long Beach'. Molina does not have to report this information before they notify the employees, and Molina will generally do it immediately after notifying the employees.
From the time Molina notifies the state Molina has two choices.
The first choice) Molina can immediately lock the workers out, take away badges, physical access, etc. However, they have to pay the worker out for 60 days of pay from the time they filed the WARN notice. So, if they file the WARN notice tomorrow, then the 60 days will be effective from tomorrow. This is what Molina is doing.
The second choice) Molina can continue to have the workers come in and report to work for 60 days, thus 'warning' the employee and giving them time to transition.
In most cases the company will choose the first option and give the worker a check for 60-days pay instead / benefits instead of having an upset worker show up for 60 days. The core intention behind the law is to provide both the state, cities and workers at least 60 days of pay and benefits in order to have some buffer to plan for unemployment.
It is irrelevant to the state if the worker is actually showing up for those 60 days or just got a check and was told to go home. The state only cares that the worker will have 60 days of income and not be in immediate need of unemployment assistance or social services.
I hope that this clarifies things. And again, this is California's policy, there are other states with fewer worker protections, but probably not many with greater protections. The Federal WARN act provides very minimal protection, and I haven't researched it too much because California law is stronger.
