 Some analysts have suggested that an alternate 'pay or play' version of the employer mandate would partially avoid these problems, by instead taxing business that do not offer insurance by a percentage of their payroll rather than using the 50-employee and 30-hour cut-offs.Furthermore, many healthcare policy analysts think it would be better to transition away from the employer-based system to systems (whether state- or market-based) where insurance is more portable and stable, and hence think that it is a bad idea to even try to maintain existing employer insurance systems.The effects of the provision have also generated vocal opposition from business interests and some unions not granted exemptions.
