I do agree timing is not good but if your suppliers are closed it poses other difficulties. Truthfully I am a bit envious as you'd never get that kind of time off as a holiday here in Canada & the USA since business dictates government policy more than ppl do.
But yeah it does make time quite tight for their projections & i have to presume they likely accounted for that. I would imagine some still did some work from home while off.
Hell we used to have a week off for xmas being a factory. Then one year they more or lesd ppsted "Good news due to the needs of the business; Xmas is cancelled!" This was announce 2weeks before hand so no one could scheduled it off. Yet this company claims to support folks having families.
