I for one can't afford to cover the remaining 25% for all my guys which you need to prove you're paying. Easier to just have them collect their own benefits individually. They're not going anywhere when this is over I'm quite sure.
I think the draft language read that the employer must make a best effort to get the employee back to pre-crisis level ie cover additional amounts. However, my understanding on this is that the government thinks its better for employers to keep employees on the payroll if they have the cash and they will cover the salary later vs having everyone run to EI and the other programs.
That being said, legislation is still not final.
