I believe that most dentists are only open 32 hours a week so that they don't have to provide benefits for their employees. It's an efficient, if uncompassionate, way of running a small business.
Here's a better idea: no benefits allowed. Cash only. Then employment would have lower barriers to entry. Two employees working 20 hours each should cost exactly the same as one working 40.
Don't know if it applies to dentists, but I know surgeon's offices are open only 3-4 days a week because the other days they are doing surgery. When I saw my dentist office was only open 4 days a week, I figured it was similar- they weren't actually closed, but they didn't schedule standard procedures at that time.
It's ironic/diabolical that SOP for a benefits provider is to deny benefits to their employees due to the horrendous healthcare/health insurance system.
I think dentists often keep short hours because they like them.
Plenty of other businesses do hire lots of part time people and manage their hours in order to avoid obligations. If you don't think that is true, well, I don't even know where to start.
Its hardly a brazen accusation. He said "I believe" and then made a fairly innocuous statement. Relax. Even still, just because your dentist is open 43 hours it does not disqualify his statement.
Accusing people of being ‘uncompassionate’ on zero evidence is not exactly innocuous - it’s sadly common on the internet, but it’s still a pretty jerk move.
